Since that AK4393/6 dacs are analog balanced signal out dacs, I suggest you to trial avoiding analog/opamp section with tapping analog L/R channels directly from pins. You have to add dc blocking cap if you will tap unbalanced signal from + pins and analog ground.

Blocking cap type and value can be determined during tests. I think 2.7 uF or greater would fit. You have to tap analog ground somewhere close to dac chip.

Just remember that I was comparing a modded board to the stock standard board. After mods the AK4396 might come out the winner.

I refer to my previous post ;

..and all this without the components being burned-in & the standard NE5532 o/p chip in situ ?



So far, I can tell you this of the Calyx dac vs my AKM4396/opa627
..the difference is not Night & day !

And later, there'll be a pair of Sowter 9545E in place of the opamp

Allan - Does the 4395 really have the better filter compared to the 93 / 96 ?

Erin - have you had similar experience of this ? I'm willing to accept that a new/higher chip may not necessarily lead to better SQ.

Have you tried emailing them? It's odd because the first one says their location is Hong Kong, and the other two say China..

Andy, I have no specific experience with this other than hearing the AK4395 in a Metric Halo ULN-2, which sounded very good.

Ok, so I've pulled up the data sheets for the AK4395 / 4396:

The 4396 goes one step further in adding DSD (direct stream digital) functionality (see - Direct Stream Digital - Wikipedia, the free encyclopedia)

Although the AK4395 chip only goes up to 192khz sampling frequency, it appears to have better specs concerning the 24bit filter compared to the 4396 ;

__IC_____________Ripple__________Attenuation
AK4395_______+/- 0.0002db_________110 db
AK4396_______+/- 0.005 db__________75db

I accept specification differences may not always translate thru to real-life experience, but in this instance it could explain the 4395's increased SQ and Allan's conclusion.

I'm ordering an unpopulated pcb an a separate 4395 ic to check this out for myself. If it can give more spacial cues & depth as previously described, then I'm all for it
