@mikelavigne please cite examples so we can all listen and comment. or come over to my room, bring your files and dac, and we can both listen and see where it goes.
or is this just more theory?
I’m going to put the onus back on you.
Please record your analog material to digital - without clipping - so you’re using the same master as source material. Level match the two sources, and record the output from your system. Compare the waveforms. If you so choose, you can share the results here.
Others have already done similar, in a listening capacity.
"My initial impression of the Pinot ADC was that Andreas had accomplished a spectacular achievement: a sub-$10K Quad DSD stereo analog-to-digital converter with easy-to-use software for simple stereo transfers from analog to DSD (in .DFF format). And it sounded brilliant! Show conditions at AXPONA 2016, of course, but even allowing for that, the Pinot was clearly something very special, working in tandem with the rest of the Playback Designs Sonoma stack.
In fact, Andreas not only gave us quick A/B comparisons of analog source (turntable and Brian Tucker’s Revox RTR) vs. Quad DSD output…all of which were very impressive…but he also did a single blind test just before the end of the show. Several of us who were very experienced, acute listeners, were invited into the Playback Designs room. Andreas did switching back and forth between an analog source and the output of the Pinot Quad DSD feed. We were given several opportunities to guess which was which.
The three of us who were invited to do so guessed wrong. We thought that the Quad DSD feed was actually the analog source! One therefore wonders: Does the Pinot’s Quad DSD sound better than the analog source?!"
"Since the Pinot ADC was only going to be there for the afternoon, we did a temporary connection to one of our LP systems so that we could do some sample Quad DSD transfers of needle drops that we would do. We used the exceptional KRONOS Pro Turntable for this task. Its output was cabled with Kubala-Sosna Elation! unbalanced cables to our standard reference, the Audionet PAM G2 Phono Amp with EPX Power Supply. That output went to the Audionet PRE G2 reference preamp, which passed the output via its balanced monitor outs to the balanced inputs of the Pinot ADC. Andreas’ notebook computer with his Sonoma Recorder software, a very compact, easy-to-use recording system, was also connected to the Pinot. This allowed us to do several needle drops and listen to them, while the notebook recorded those drops to DSD .DFF format.
Those transfers turned out incredibly well. A quick listen to the results, before the Pinot had to be packed up again, indicated that the Quad DSD transfers were indistinguishable from the KRONOS playback that Andreas and I had just heard. One was the opening track from Dream with Dean on Analogue Products QRP 200 gram vinyl; then we did a sample track from the brilliant reissue of the Decca Espana with Atualfo Argenta (incredible album and transfer!), and finally three tracks from the excellent recent reissue of the MPS LP How I Really Play by Oscar Peterson. Really breathtaking, believe me."
"The Pinot Quad DSD ADC arrived very recently, and I haven’t had sufficient opportunity to give it extended trials. Nevertheless, my listening sessions at AXPONA 2016 with the Pinot, as well as the brief time that I worked with Andreas to do some needle drop transfers to Quad DSD in late May, using his Sonoma Recorder software, show that the Pinot is a superb analog-to-digital converter. The results with the Sonoma Recorder app were mind-blowingly good, and reasonably easy to do, giving the real feel of LPs/tapes in Quad DSD mode. Close your eyes, and you might as well have the RTR in the same room…"
