in essence, the 'noDAC' is nothing more than a powered isolator. I tried it and concluded that the main sticking point is sample rate. If the DSD rate is 256 or higher then the top-end filters can be less destructive. In the end, the sound was not sufficiently improved for me to put in the work to transition my atypical system. I remain interested in the cause for the sonic differences between PCM and DSD, and my working hypothesis is that some artifact of PCM is actually manifest at the level of driver cones. ...which is consistent with the range of reactions to the 'noDAC' method, as the properties of our speakers undoubtedly vary tremendously.

Yeah in some systems DSD128 was the big improvement with some not noticing any big change between that and DSD256. Other systems swear by the improvements gained by shifting the noise into the higher spectrum. I'm sure some systems prefer PCM over a noDac. I think it depends on the implementation of the noDac or the DAC. I plan on copying hazard's latest noDac efforts. As far as isolation, I will be using twisted pear teleporters, which should handle that.

Wondering if high quality, naked foil resistors, or exotic caps would make a difference in this noDac circuit? I mean we normally take great care with anything in the audio path. But is it necessary here? This is sort of a hybrid ana/digi, right?

Anything affects the sound Mcspack its only a matter of whether its better or worse.
Lots of testing of parts involve though.

GREAT NEWS! if you are successful I would love to buy a noDAC from you. or maybe you can post a step by step tutorial so i can do it myself? maybe you can make a new thread and the first page of it should be like a work in progress tutorial thats being updated

that clearly demonstrates the multi Mhz spikes you feed straight into your amps...

I don't know what the latest circuit looks like, but assuming you are referring to a reconstruction filter: the reconstruction filter is completely analogue and handles the desired signal as well as a lot of high-frequency quantization noise. Having components with reasonable high-frequency performance (which implies reasonably small size and short or no leads) will be more important than in a "normal" audio circuit, everything else is just as critical or as uncritical as in a circuit that only handles the audio signal itself.
