@rauliruegas , thank you for saying that first. If I have to use a standard to AB against it will be a 24/192 digital file. Nothing at this date is more accurate than a 24/192 file in a home system. Why not DSD? None of the modern four channel digital processors I know of operate in DSD, always PCM. The digital program I use to play files converts DSD to PCM for playback and storage.
No analog tape machine can compete for accuracy with a 24/192 file. This says nothing about perceived sound quality. I intentionally juggle the frequency response curve to suit my own taste, intentionally inaccurate.
What Mike's Studers are, are very cool machines, mechanical artwork. They are antiques and have no place in a modern system. They are now much more cost effective better performing ways to have the highest quality sources.
Today I had the experience of using the Platinum Signature played through a current mode phono stage without RIAA correction, digitized, pops removed and RIAA correction applied digitally. I would call the results majestic. With this cartridge the current mode is noticeably better than the voltage mode. I can switch back and forth. The current mode is slightly cleaner with sharper transients which increase detail. Higher volumes are even more comfortable. The two places the improvement is most noticeable is with pianos and bass definition. Very happy with the results. Now I have to learn how to "render" files. The system records them flat like raw photography files. If you want to play the files from and store them in a normal library they have to be "rendered" by adding RIAA correction, adjusting gain and using other added features like pop and tic removal.
