Since last couple of weeks, I have noticed that vibration isolation of dac/pre/power is having a profound difference in the tonality of the sound in my case. My speakers don't like vibration isolation and I prefer them without the cerabase footers I bought. I dont know why that is. But dac/pre/power are getting me to drive crazy. I have tried cerabase, wood, plastic, rubber, metal and each gives a characteristic sound, some dull and earthy and some so airy and metallic. Please guide me what else can I try and why there is so much difference, can it be because the equipment is not well designed or what. Can it be because I live on 17th floor of a building, maybe it vibrates more higher we go

I won't say it's due to design of equipment not being good.
Even in very high end setups I have noticed the sound changing depending on the material of footer used except for maybe one or two setups.
So nothing wrong with what you are experiencing.
But it's little tricky to tell what may work for you because every component will react different and every one of us hear differently.
At the same time I can understand it's not simple to try everything before buying

The type of footers that works for a given setup also depends to a great extent on the type of rack/platform used. I use hardened glass shelves. Ceramic or steel ball based footers frustrated me. They harden the sound. What works for me has been a sandwich of foam rubber and natural cork. It might work for you too.

Yes I found them good. I have two on wall behind listening position also. I would never listen without them, highly recommended if you have plain walls like I have. The foam bass traps on top corners work wonders.They make echoes go away and help imaging a lot, especially vocals. I have experimented alot with these. If I remove them and listen, it will not be as pleasurable, Mine is a small room, these things help alot, maybe in a bigger room they won't. I wanted to get diffusion panels but they are very costly until diy, so got stuck with the absorption ones. But too many absorption panels also deaden the sound and make it unnatural. Foam is lightweight so can experiment a lot with it.
At Heliumflight's place it was bare walls. Keen to know your observations

Yes bare walls do have an echo, especially bare corners muffle up the sound. I have realised few things regarding diffusers/panels based on my experience.

- A proper wooden diffuser helps in bare walls as against any foam/absorption panels, i have now removed the absorbers behind speakers that were in the pic, they can deaden the sound.
- realized, bass traps on top empty corners always greatly help, infact they are a must as far as i am concerned for any critical litening
- these things need to be placed far away from speakers/listener to heave desirable effects.

In that particular room, I think bass traps on rear wall top corners would be interesting to hear.

New audiogd r8he dac playing at home now. That completes fully balanced audiogd chain for me, was itching to go all balanced for quite some time now.

New additions to my system:

1) allo shanti psu
2) furutech cables for shanti, dac and amp
3) changed acss cables to mogami 2549.

Allo shanti psu is very high perfoming psu imo. I am using it to power my mi box and dirty side of allo digione signature. It marks a significant difference for me for both equipment. Its highly susceptible to different power cables and upgrading its power cable to furutech fps022n has brought it to a new level with increased resolution and smoothness. Stock cable sounds grainy in comparison.

I have changed audiogd stock acss interconnect cables to mogami 2549 which has brought down high frequencies, decreased soundstage but increased bass and has made voices more lifelike. I also experimemted alot with balanced vs acss with same cables and acss clearly wins the competition, unfortunately it works only with audiogd components.

I am using furutech tcs21 power cable with my dac and fps55n with power amp. Both are excellent power cables but they can make my system analytical so i am using lapp power cable with my preamp to balance out things a little. Though these cables are shielded i am not connecting shield to ground earth for all my power cables cables as i have noticed it makes bass more lean and sounds unnatural though it increases sound clarity. All cables use furutech connector at equipment end. I found its not worth using good cables without good connectors, they being important than cables themselves. Trying different power cables is really fun.

All in all i found power quality contributes a lot to a hifi system. My system sounds best after 11pm and worse during evenings. All mew changes. Have made my system sound a little analytical. I dont know what exactly the power cables do especially without shield connected to ground but they do affect the sound in a positive way especially the way the connectors affect sound is really magical.

An idle brain is a devils workshop, causing the itch

Back to audiogd interconnects now which are basically canare cable. They are more entended in frequency spectrum and more revealing than mogami 2549. Dac is fully burned in now which took around 2 months. Overall soundsignature is soft and smooth, full of richness and naturalness in tones, very very musical and engaging. Not a hint of harshness or agression anywhere, though i can hear lot of details.

Digione signature is a little more bright than usb played from pc. I am liking usb more these days as i find it more musical and smooth, maybe the dac suits usb more. I tried converting few of my flacs to wav couple of days back and played via foobar, the difference in sound was more than expected, especially in lower frequencies and separation. Now it seem like two subwoofers are playing in the room, never before i got this feeling, bass in not lean as before and it was never as smooth. I feel its very true that its all about source, whatever it is i am very happy for now. Next step should be some power conditioning and usb to i2s convereter.

Friends, i am using furutech connectors only on equipment end for all power cables. Wall end still uses anchor plugs. Does anyone know if replacing wall side connectors also with furutech plugs will make sound any better and if its worth the money. They did made a significant difference on equipment end.

So magic is in some proprietary medium of transfer whhch only audio gd dacs support or you use spidif or aes to connect this device to your dac?

For you you have a transport with coax out so common sense would say why should I add another device in between when digione signature by itself is so good ?

So what made you believe before purchasing it that this will surely work for you ?

Ofcourse , after listening it has worked really well.

Its not any proprietary medium of transport which audiogd dac supports only. Di20he is a digital transport which has usb and spdif coax inputs, then it reclocks and does something to the signal to output spdif coax, i2s hdmi (psaudio standard), aes to any dac that supports these inputs.

In my case, digione signature to di20he is coaxial connection, then i2s hdmi from di20he to my dac. Whatever this thing does, its doing it brilliantly. I never had plans to buy this thing keeping in mind digione signature is itself very good, but seeing the sort of sale records kingwa is breaking with this product on headfi, i had to get this. Indeed it has turned out to be magical to my surprise.
