Setting up a modest HI-FI system.

If you really need to try out room correction and dont want to try out software solutions on a pc, then keep the streamer and dac as separate devices. At a later point, introduce a device like the one below in between those two and see what it does.

Goodness gracious!
I got a Minidsp SHD 5 years ago....still trying to figure out how to use it though 😂

So got a Dspeaker Antimode 2.0 next, which is a completely automated correction system, and is a breeze to setup and use. So best to stick to automated solutions like Dirac, Ypao and Audyssey etc....

And if you are looking only for correction in the bass, for a two channel system, and dont want to faff with PC driven software. Then the above mentioned DSpeaker Antimode 2.0 works a charm :)

Looks like the device works in both digital and analogue domains. i see both type of ins and outs on it. So you can connect before or after dac ?
 
Frankly, I am just beginning. So, I'd rather have the machine make all the decisions regarding DSP and room correction. It can be the streamer or the amplifier or the speakers or even another box in the chain. I just don't want to go into settings and start fiddling around. Too much work for a guy with a full time job, mobility issues, and not enough space on the shelf.

Hi :)

Yes. We can use it as a correction system in the digital domain and feed a separate DAC if required. However, let me explain a bit on how I used it, for better understanding. And I dont want anyone buying it on my recommendation alone 😂 😂

When I first got it, I was feeding the secondary output from my preamp, into the analogue input of the DSpeaker. Then this signal went through a ADC stage, and was corrected upto 250 hz ( My bass cabs were running below 300hz, besides my rooms schroeder frequency is 250 hz ), and the corrected analogue output then was fed to the power amps driving the bass cabs. With the correction enabled, the excessive bass boom was culled. And this was equivalent to the lifting of a sonic veil, and added immensely to the lower mid range clarity. However, on prolonged listening, there was a feeling that the additional ADC / digital correction / DAC conversion, were all adding up to processing latency, and bass was a bit delayed compared to the mid range and upwards.

Then I started using it as a pure dac with correction for the bass cabs only. I was at that time using a Metrum ambre as a roon end point. So I fed the coaxial output from the Metrum ambre to my main dac, and its down sampled optical output to the DSpeaker. And the mid range and upwards were driven with separate poweramps from the main dac. And bass cabs via separate power amps fed by corrected bass signal from the Dspeaker.

The central volume control at that time was handled in Roon. I only once configured the levels on my main dac and Dspeaker, and then left them untouched. And all subsequent volume changes were handled in Roon. This worked beautifully, and my bass woes were gone. But then my digital Roon chain became too long and too complicated with several boxes and linear power supplies. So i finally quit roon. And Iam not using the Dspeaker at this moment in time.

Subsequently, I learnt that the processing latency of the Dspeaker is exactly 3 feet in distance. Which means , my bass cabs should have been closer to me than the main speakers by 3 feet. And this would have solved the issue.

So if considering the DSpeaker today, I would whole heartedly recommend it as a fit and forget automated bass solution, as long as one has twin outputs on his preamp, and only uses it for the subwoofers and has room to place the subwoofers closer to him than the speakers by a minimum of 3 feet. And with the advancements in dacs today, it is no longer relevant in a high fidelity 2 channel system as the main dac running the main speakers. But for subwoofers, it is a god send.

P.S - And please disregard that Amir's review you see on Audio science review. This is a bass correction system that by default works upto 150 hz, and max upto 500hz. And this is where its performance is optimized. However, Amir runs his usual test signal and measures Sinad at 1000 hz which is well beyond the optimized operating frequency of this unit. And additionally I found that using a 12 V linear power supply, was a big improvement over the inbuilt SMPS power supply. Hope this helps :p
 

The above is a excerpt from Audiogon with discussion on the antimode. Please read till the end, to find out how to use it properly. The poster ozzy who started out not liking the Dspeaker, ends up loving it with his JL fathom subs. And prefers the Dspeaker's correction, over the inbuilt correction in his subs. In his case, he is running speakers full range, and subs running below. Bass at such low frequencies has very long wave lengths, and thus even with his subs placed 5 feet farther away than the main speakers, from his listening chair. He doesnt perceive any time delay.

In my case, I was running my bass drivers from 300hz downwards. At this higher frequencies with shorter wave lengths, a time latency equaling 3 feet in distance becomes audible. Hence, my findings above.

And before anyone thinks I might be willing to sell the Dspeaker antimode, then thats a big no. And neither am I selling the minidsp SHD. Had to post this, as my endorsement of the Dspeaker is almost sounding like an advert 😂 😂 .

Iam building twin compact Scanspeak revelator subs to go with the existing Rel. The idea is to end up with a distributed bass array, all powered by DSP in the very low frequencies. So the Dspeaker will again come out of its closet in the very near future :p
 
I am sure you have scared the OP away from the hobby itself :)

In a modest system, can one just split the signal from a subwoofer output coming from a 2 channel receiver using a single to dual RCA cable and connect it to this device for bass management ? btw, I never knew this device only works upto 500 hz.

You have just hit the nail on its head 😅

Haha... I was mildly aware that I was treading on slippery slope by describing my complex use case scenario. But just wanted to share its functionality in full :)

Coming to the query, if the 2 channel receiver has only one output for a subwoofer, then the Left and right bass channels will be summed internally to mono inside the receiver. So we can use just one Rca cable from receiver to Dspeaker, then a single Rca cable from Dspeaker to the subwoofer.

Bass once summed mono cannot be undone. So even with twin subs, one connected via XLR out and the other via RCA out, both will play mono only.

Thank you, sir, for simplifying things for a newbie🤪

You are most welcome sir :)

Just to add to the above, it is recommended to use even two subs in mono and not in stereo mode, for better balanced bass. I have'nt tried that personally, so cannot vouch for that. But that is the recommendation from experts :)

Lovely, more science for someone who barely managed a B.A degree. Getting into the wrong hobby here, I can see 😅
 
Naim and Focal have an outlet in Delhi. They have offered a home demo. The Uniti systems by Naim are all-in-one. We just need to add bookshelves and a sub (I would like to skip it though, if they can suggest suitable speakers). Another option they have suggested is a streaming amplifier connected to focal bookshelves.

By the way, what to look for in bookshelf speakers and streaming amplifiers?
 
Got a home demo of Focal Aria EVO N°1, Naim Uniti Atom and Marantz 1200NR. Can see 1200NR only in the archived section on Marantz website, so not going for this. The vendor can get me Marantz amplifiers, so am trying to decide between Naim Atom, Marantz Model M1, Marantz Model 40n, Marantz Model 60n, Marantz PM 7000n. But essentially between Atom and 40n. Atom is 300,000 MRP, 40n follows close at 2,79,000. What sort of discounts can I expect over the MRP? Also, will I be able to play high resolution music without getting down-sampled (if that's the word) over Wi-Fi?
