In my main system, analog sources are digitized so as to be processed for (1) level trim (0-8dB reduction) aka volume control, (2) DSP for crossover, (3) DSP for room EQ, (3) delay for time alignment, (4) various flavors of limiting on the subwoofer bass to keep from overloading. I do this for vinyl, FM, tape, and also DRM digital recordings such as DVD-Audio where the high rez digital is hidden, and SACD which is not pcm. I do not find this compromises quality audibly. If I run unprotected digital (CD/SPDIF) straight or redigitized, it either doesn't sound different or more often than not, the redigitized version from my ADC (at 24/96) sounds better than the original. For this digitization I use Lavry AD10 (ADC) and take AES digital output. Recently, to make dubs, I send the AES output to an Alesis Masterlink for recording at 24/96. Few consumer products will record SPDIF anymore, especially into Windows 10 it appears (my Emu 0404 no longer works). I've never measured it, but the Lavry specs at 117dB S/N IIRC, which could be 26dB better than a direct digital connection through a AV processor using HDMI (counting the analog output of that device). I have a slew of similar ADC devices, a PAD-1 from MSB, a Sparrow from Black Lion Audio. If I won the lottery, I'd buy a Lavry Gold (130+dB) or Weiss ADC. The PAD-1 and Sparrow are cheap used if you can find them, but these are all SPDIF and/or AES output.
I only use Win10 for measurement purposes, and for that, a Focusrite Scarlett 2i4 is now essential kit.* My Emu 0404 no longer works on Windows 10. Early reports of using Lynx Hilo on Win 10 were not encouraging, otherwise that would be the "ultimate" (strangely looks like a metal boxed version of Emu 0404). I use ESI Juli@ card in a WIndows XP box for RMAA. I have a Turtle Beach Fiji card in a Windows 98 box for LAUD 3 (currently not working).
*The Scarlett, like everything I know that still works on Windows 10, has no SPDIF type digital input so I can't use it with my other ADC's.
