I had a long conversation with Mr. Ashish Aggarwal, CEO of SNAP Networks on the 28th.

First a little background. A few of us did a review of SNAP Networks Violet speakers some time ago. Please check http://www.hifivision.com/reviews/14798-violet-speakers-true-wireless-ht-system-review.html for details on the review.

The review, naturally, did not sit well with Ashish. He immediately contacted Ram and me for a second meeting and a demonstration under his guidance. Unfortunately Ram was very busy and Ashish was travelling between Bangalore, Mumbai, Delhi, and the US. We had to wait for nearly 9 months before I could meet Ashish. I did meet him today, though for a brief 60 odd minutes. Here is what we discussed.

A Little Background First
Ashish did a BE in Electrical Engineering from VJTI and then went on to get a PhD in Electrical Engineering from the University Of California in Santa Barbara. He specialized in DSP where he has gained a lot of expertise. His passion for research into sound started early. After his PhD, he led a team of 8 people and developed part of the algorithm and software for Apples iPod. This was in 2003. From 2003 to 2008 he worked with Harman International where he architected and developed whole home media network solutions, new audio algorithms and DSP software for high end systems, and media servers. He was directly or indirectly involved in the development of some of the best products that came out of the Harman group including JBL, Revel, Infinity, etc.

While at Harman a friend, who was also a PhD, threw a question at him that changed Ashishs life completely. His question was simple why are HT systems so complicated to set up and use? If I, as a PhD, find it difficult to install these systems, what will the status of simpler folks? he elaborated. As an end user, I just want to enjoy my music and movies, not play around with your systems, he concluded.

Ashish remembered his college days. As a grad scholar in Santa Barbara where there were very few Indians, Indian food was not easy to come by those days. So he built a complete HT system on a backpack including a projector, and he used to travel to houses of Indian acquaintances to show a bunch of guys a new movie and get tasty Indian lunch or dinner in return. He had to travel to LA many times from Santa Barbara to get his hands on new Indian and Hollywood DVDs. He used to be called Chalta Firtha HT.

In those 5 odd years, HT systems had got more sophisticated and more complicated. Connections were complex as was the wiring needed for speakers. You had to worry about wire gauge, impedance, resistance and a lot of other technologies. What his subsequent work at Harman showed him was that in pre-sales, nearly 60% of potential clients just walk away from a HT sale as too complicated. After just one experience of setup, 50% of HT owners never install the system again. And, you have some 300 multi-million dollar companies running after the remaining small number. In the US, a good installer will charge $200 an hour. In India also, installers charge a sizeable amount. 90% of the people who do not use professional help install their systems incorrectly.

Thinking about the issue, Ashish came down to two major points that needed to be fulfilled. One was that a HT system should be as simple as switching on a light bulb. Second, it should sound good.

First, the simplicity. To remove darkness, you switch on a light bulb. Can you remove audio darkness by switching on a speaker bulb?

Ashish initially came up with an idea for simplifying all this a universal cable. Using a networking principle, his idea was a router box that identified each input/output device that was connected in a manner similar to what happens in a computer, all using the same cable. The name? Synchronized Network Access Protocol or SNAP. The only issue was a hitch he came across immediately. How do you convince 300 odd devices manufacturers to fall in line and use his single connection methodology? His idea, SNAP, was dead before it started. After contemplating for a while and speaking to friend and well wishers, he decided to evolve a marketable product using the idea. The simplest was a powered speaker with networking capability. Thus the Violet was born.

But, there was an issue. If the speaker needed wires, there was actually no change from existing systems. Companies such as Meridian were already doing that. Ashish continued to be fascinated by the single box or router concept. Why not receive all signals into a simple box, and then network the powered speakers to the box? Why not remove the wires completely? The concept of the current Violet System had taken birth completely.

With wireless, the first issue was jitter in data transmission. Sound was being transmitted as a packet. The timing and packet accuracy was essential to ensure that there was no jitter. Ashish worked on complicated DSP to set up a two way signaling between the box and each speaker to ensure accuracy of data transmission. He managed to take each speakers efficiency upto 200 pico seconds. Ashish ended up with a huge speaker box that had a PC inside, an amplifier, and a single speaker driver inside. Obviously this was an unwieldy system, but it was processing signals perfectly.

Simplicity has been solved. What about good sound?

Ashish was a little weary of asking audiophiles what good sound was. That was not the market he was looking at. He wanted a mass market answer, and the one he got was that a cinema hall sounded good. Another answer was that Bose sounded good. From an initial dislike for Bose, Ashish decided to take their achievements more seriously and see what they had done.

He went back to the drawing board. He placed a speaker inside an anechoic chamber and tested it on-axis and off-axis for frequency, distortion, and coloration. He then used the same speaker and did a blind test with a few friends. The results were different from each other by a huge margin. This was for a single speaker. Then he came across another idea. He tested the speakers for a 5.1 and, surprisingly, the differences disappeared completely. It was at this instance that he realized that Boses Direct/Reflecting speakers system was achieving this by creating a sound wave close to that of an omni-directional speaker. Directional speakers need to be phase aligned for a particular hearing position. Omni-directional speakers, on the other hand, are coherent across the room. The Violet speakers take Boses concept one step further. Using omni-directional speakers, Ashish created an infinite wave system that filled the room with sound and made the speakers disappear completely.

Ashish had now solved both issues simplicity and good sound. The Violet system has a simple box as a central router that can talk to any number of powered speakers that can be placed anywhere in the room.

He still had one issue to solve. And that was to make the product of a size that was simple to install and pleasant to look at. Obviously it cannot have a PC inside. But that was an easy problem to solve. All the DSP done by the PC could be written onto a single microprocessor. The larger and more difficult problem to solve was the speaker driver. Ashish did not like the concept of directional speakers that forced you to sit at one place, place the speakers at a particular place, and do minute adjustments to the speaker directions to get good sound. He wanted his speakers to be placed randomly across the room, he wanted you to have the freedom to sit anywhere and yet get good sound. So he switched to omni- directional speakers. He wrote the DSP into a silicon ship, he developed a small amplifier, shaped the speaker like a light bulb, and you have the Violet speakers. Connection was as simple as plugging a light bulb. He even created two light bulb sockets one that can be placed on the ground or hung from the ceiling and another that can be hung on the wall.

Ashish had started the company with the help, blessings and funding from relations, and a few friends. Even after proving such a concept, Ashish failed to excite the community to fund his vision. When they saw Ashish proudly displaying the huge box, they were disappointed with what he had created and decided to back out politely, and so did the other co-founders. Ashish was now left alone with an idea he knew could be taken to the next stage. Ashish reformed the current team, stretched every rupee he could and took the idea to production and then to the market.

The Present and Future
The product that Ram, I and others had reviewed was literally version 1 of the Violet system. Our review made Ashish go back to the drawing board a little. Since the whole development was being done in India, he was finding it difficult to get a individual or a company to design a good sub woofer for him, As a DSP specialist himself, he was getting frustrated with the response and results from Indian designers. So he ended up in China and located a manufacturer who could design a good sub, and also incorporate Ashishs DSP and amplifier concepts inside.

What is in the market now can be called version 3 with a vastly improved sub woofer that provides a stronger and deeper low frequency sound.

I still had one issue with Ashish. How did he plan to solve the Codec issues and what about the connection between the player and the Violet box? Currently you have two options. One is to set up a digital connection using a coaxial digital and get just Dolby Digital sound. That is what the Violet has license for. The other option is to let the player decode and connect using 6 analog cables. The second method is a bit unwieldy, and kills Ashishs original need of simplicity. Ashish does not want to complicate his box by adding more decoders. Each decoding costs $14 per piece, and adds to the cost!

Enter HDMI 1.4. According to The Blu-Ray forum, all Blu-Ray players with HDMI 1.4 are mandated to decode all audio signals. The Violet version 4 will have a HDMI 1.4 input and can be connected to a Blu-Ray player easily. When this happens, Ashish feels the AVR will become redundant completely. That is his objective to eliminate the AVR completely. A bold plan, half of which he has already achieved.

Next step, Ashish said, will be to make the player obsolete. He mentioned two emerging trends to do this. One is web based sites such as Netflix that allowed you to pay for and play a movie from a centralized server. The second was the introduction of solid state drives. 1 TB solid state drives are working in R&D labs, and something like 250GB have emerged in the market. Imagine going to a shop, picking up an empty 50 GB solid state drive, choosing the movie you want to see, and getting it written onto your drive in a few seconds? Bring that home, and insert it into a slot on your Violet box. And you are watching a Blu-Ray movie without any optical media.

Interesting, I thought. Will really be a wonderful world, I am sure. Something close to what they show in Superman movies and in Star Trek. In Star Trek, data is stored in three dimensions on a long crystal. You insert the crystal into a reader, and multiple laser beams read the data from three planes. I know for a fact that such a device exists, and is just a few years away from being marketed.

Ashish has taken a second mortgage on his house to fund SNAP Networks. His wife continues to work in the US. He has had two children in the three and half years he has spent in setting up and running SNAP Networks. That is the passion he has for his ideas and products.

Looked at from a different perspective - simplicity and good sound - the Violet system is brilliant. Ashish needs to be praised as well as helped to become successful.

Ashishs journey and that of SNAP Netwroks has been one of true commitment and grit. First was proof of concept from wireless and audio quality. Then came miniaturization. Their angel investors have supported them all the way. It is the external investors that shied away and the three other co-founders that left the journey. Only Mr. Bhaita (their Chairman) and Ashish stayed on the course. Through all this he also added a 3 year and a 9 month old baby to his family.

Ashishs Indian operations consist of 30 odd R&D engineers. He has a production facility in Bangalore as well as sub contractors from whom he gets various parts of the system manufactured. In spite of being very patient, he could not get any Indian company to re-design his sub, and had to go to China for that.

Something tells me he is sitting on a gold mine. He has already sold 500 odd systems in India. He has seen people picking up the Violet system in direct competition with Bose systems. He is now working on expanding his market reach through retailers such as Chroma. In my initial review, this was the route I had suggested.

The concept of Violet is to trust devices instead of people. Pick up a system packed in a box with a handle, place the bulb holders where it makes sense for aesthetics, insert the speaker bulbs, connect the main box to a player with an HDMI 1.4 cable, and you have a home theatre ready. How much time should that take? 30 minutes? No room acoustics, no worrying about cabling, no change to all your precious stuff in the room. If you dont have place on the floor, just hang the bulb holders on the wall or even from the ceiling.

He has my complete support. Well done Ashish.

Ashishs next idea? How about a 2 inch cube that can generate 100dB of sound? Sounds impossible? Not with Ashish.

George, can you take this one step further and visit Ashish in his R&D and office? I would like to see some snaps and also get a different perspective.

Cheers

Nice concept and really innovative.. Congrats Ashish (dont know whether he is reading this).

One suggestion (its only my point of view) is that the Bose is sold only on the brand value and compactness. I am not sure unless the violet buildsup a good brand value in the market (dont ask me how:)), if it tries to sell through Croma/Reliance marts, it will not be noticed by the market as the market is flooded with cheap and compact units from china and other local brands. People will weigh this also in that category, nobody will think about the technology behind it since the normal mass will think that "afterall its only a speaker". I dont think even Bose will not be widely accepted if it is sold through these outlets.

I think it should be highlighted as a lifestyle product for the common/middle class (pricing should also be in that category). Since its a lifestyle product it can be distributed through some lifestyle showrooms like @Home/HomeTown (i think nobody is doing this) by emphasising the compactness (those showrooms displays their product as part of demo rooms similar to the rooms in a house). Apart from living room, they can highlight the usability in different rooms (eg, for a bathroom with waterproof speakers). They can also concentrate on audio distribution systems (eg hotels). Anyways, the concept has a lot of potential. Happy to see an indian audio company budding ...

I agree with Sajith.... I myself was flabbergasted when I saw the speakers the first time and heard them...they need to be marketed as lifestyle products and when the brand is built it should be made available to everyone...
 
From the day I have heard the violet system I have been one of their serious advocates. Forget everything the convenience that this system offers is unheard of. You just need a couple of power points one in the rear and one in the front. Well as the concept was fantastic and Ashish was very flexible in his approach that he could have any sub that the owner wanted fitted with the wireless module or you could use it with the wire. My only grouse is that it should be priced a little bit lower as it is priced at around 65k presently. I would definitely recommend this to people having Oppo or sources having good DACs in HTPCs and not needing video scaling. This will beat many existing systems hands down and coupled with the convenience it offers like shifting the total system to second room which can be achieved in minutes this system is a no brainer.

A good write up by Venkatji

I met Ashish much before they released their Voilet system. Whatever may be the positives or negatives of their system, one aspect that stood out is his passion and drive. I hope he finds much success !!

cheers
 
Nice and very well written by venkatcr.

The concept of Violet is just great.

"50 GB solid state drive, choosing the movie you want to see, and getting it written onto your drive in a few seconds? Bring that home, and insert it into a slot on your Violet box."----sounds great and also cheaper alternative, but what about the legality/competition from bluray disc manufacturers? Are you talking about very distant future?

"The Violet version 4 will have a HDMI 1.4 input and can be connected to a Blu-Ray player easily. When this happens, Ashish feels the AVR will become redundant completely"----this is simply even more brilliant, i think then the cost of 65k or more is justified. Venkat sir, when this version will be available in north india , i mean chandigarh, delhi etc.

Thanks
 
Imagine going to a shop, picking up an empty 50 GB solid state drive, choosing the movie you want to see, and getting it written onto your drive in a few seconds?

Sounds like flixonstix. Did they even go beta? Nothing to imagine, it has been tried and (probably) didn't work.

How does he plan to write 50GB in a few seconds? Unless you carry a SAN in the back of your truck :)

Another *visionary* who didn't do his homework?

ThatGuy and Mandeep, you must remember that software owners are looking for ways to protect their IP and will jump at anything that gives them an opportunity.

Online movie distribution is absolutely safe for them because, you never get your hands on the media.

The use of solid state drives is increasing day by day. New PC cases are providing special areas for the installation of solid state drives.

In terms of speed, USB 3.0 today allows you to transfer a full 25BG Blu-Ray movie in 70 seconds at 5 Gbps. I am sure internal speeds will increase. You do not need a truck. All you need is a resident NAS and multiple terminals.

The creation of Flix on Stix is very much alive. More than anything else, the usage of solid state drives will be safer and longer lasting. They will not have the vagaries of optical media.

You must respect visionaries. They are ones who brought you the CD, DVD, Blu-Ray, USB, solid state drives - all the facilities we take for granted. If you start thinking of everything with a stilted mind, there will be no progress. Remember, visionaries take enormous risks and think beyond what is a available today. Five years ago I used to watch with a hanging jaw at what they showed on Star Trek. Today the use of crystal for data storage in 3 dimensions is reality. Today the use of air to display images is reality - aka what they showed you in Start Wars. Philips already has tested and got a patent for a paper thin screen that can cut to the size you want. Voice recognition is a reality. The day is not far when a box made by Ashish will ask you what you want to see or hear, completely removing the need for a RC. 'I am in the mood to see a James Bond Movie' is all you need to say. 'Increase volume', 'Enhance bass', are some of the other instructions you can speak.

Can you, for example, even imagine a HT without an AVR or a player? That is a vision.

Cheers
 
but what about the legality/competition from bluray disc manufacturers? Are you talking about very distant future?

Venkat sir, when this version will be available in north india , i mean chandigarh, delhi etc.

The media and distribution is controlled by software owners, not by manufacturers of media such as Blu-Ray, though they work together. They moved together from tape to DVD to Blu-Ray and they will move to the next step in it's evolution.

I am sure Ashish will make it available across the country when it is ready.

Cheers
 
Hi Venkat

I met Ashish last year, I think, before his commercial launch and posted a brief write up here about his product.Let me see if I can find it and see what I wrote about it.
 
Was eagerly waiting for this write-up. As always well structured and presented. If only he had given little advance notice, i would have made it. I am looking forward to hearing the V4 now :) as I am looking at upgrading my HT soon :)
 
I was expecting the violet stall in the Inside-outside exibition at Bangalore (Cinibels with klipsch ref HT setup and Torvin stalls were there).
 
I understand that these are now available in the Croma storesI met someone who knows Ashish and jumped on board a pre order special, who mentioned this to me a few days ago.
 
When will version 4 with hdmi 1.4 be available? The version available now has what inputs? hdmi 1.3??

The present version is available without any HDMI input, it just have couple of Digital Coaxial Inputs, 2 Stereo Analogue Input and 1x 5.1 Analogue Input. As per my understanding and a brief discussion with Dr. Ashish Agarwal his new box with HDMI ver 1.4 is ready but he is fixing few issues with it and will be releasing it somewhere during March 2012.
But he has also promised for an upgrade to old customers at nominal cost so anyone who is looking to buy the present system can do so and then wait for the newer Box with the HDMI to be released and then he or she can upgrade the same.
 
Good Review and introduction, Wondered if Dr.Aggarwal considered using alpha TL for his sub-woofer design. It would have sounded best with his Violet speaker. I have made some designs with these theories and are very compact and best sounding sub-woofers for 5.1 setups.

Cheers,
