DAC sound

Yes, all they are finished and tested. The sound:
Very detailed, but:
-AD1852 internal DAC /in CD w/o resampler and CS8415/ outperforms a lot the AD1955 DAC with AD8066 based I/V stage
- AD1955 DAC with resampling and CS8415 , as I've mentioned, is worse than the AD1852 in this configuration. I'll do some research to find why is it so! The soundstage is not wery well focused, especially the vocals. THE AD1852 internal has very goodd soundstage , and stable, fixed.
- My old AD1852 + AD1892 DAC clearly performs better than the AD1955 one, and similar to the new AD1852 internal.
All these DACs are with some modification of Elso Kwak's KC7, and LM317 or TL431-based regulators.
Thanks my friends who helped me with testing,
thanks to ELSO Kwak for his fine clock circuit!
More results to come!
regards

I bought the AD1955 evaluation board from AD website for $167. Looks pretty nice, comes with a balanced output, too. Now I just need to build the power supply and see how it sounds.

Дака ти е станал екстра , а какъв ти е офсета , и пробва ли да го пускаш на 96 , 192 кхз ? Имам подобен китайски кит , който сглобих обаче като го пусна на повече от 96 кхз пращи , имам чуството че е от буфера , вече дръннах едно ЛМ-че

Dhaka has become your extra and what is your offset, and you try to drop to 96, 192 khz? I like Chinese kit, assembly of which, however, it dropped more than 96 khz crackling, my feeling is that the buffer has an LM-drannah that

The loss by google translate are to large for exactly understanding (even by translate to German).

Last post 308 is an interesting solution for I/V but did it works like it should ? And the bane in here is those 10 UF cap + 2200 UF cap , I believe they are electrolityc ?
