this dac is non-oversampling. i don’t believe in upsampling.

I am building a preamp with EVA, Nelson Pass buffer and a selector. There will be an evaluation of EVA pre and transformer volume control. (Sorry off topic).

Its just the difference that counts, so even a noisier amp like a tube can reproduce a difference of 100nV, because there are already louder bits playing. Nevertheless I would like to stress the importance of a noisefloor as low as possible.
Most of us still listen to CDs, and there are excellent dacs around, but 24bits are an improvement, and even 32bit dacs are not nonsense, the “spare bits” can be used for mixing and processing in the studio or for a loss-free digital volume control at home.

Looking at the table we see, that Vinyl records at lets say 70dB (already excellent) would have a equivalent resolution of about 12 bits, must be wrong, because we all know, that their resolution power is often better than digital.
My Denon cartridge has an output of about 250u(micro) Volt and about nanovolts at quiet sections. I have to be careful, that the tiny signals can be heard, this is difficult, but possible, and necessary for a lively reproduction. Nobody would deny, that these tiny signals are audible if amplified.
Will be continued

do you mean do i sell the pcb? sorry, no intention for doing this at all.

the chips and resistors are all surface mounted, necessary in order to keep the signal path short. it’s quite a nightmare to build.

if i were to offer pcbs, the support alone, and the remote trouble shooting…. wont leave much hair on my head!
