I'm sitting here listening to my rig with the RWA modded SB3 in place. With every file that I listen to, I say to myself "I just gotta' tell somebody how good this sound is".
Two reasons held me back. First, I know how tedious it can get hearing somebody go through the same old deal about their system. Second, listening is so good, I would rather spin tunes than write about it.
PC audio via the SB3 is really a brilliant solution. In my system, everything is better. I.e. treble, bass, detail, timing (especially the timing). Tonalities of electric blues guitar, Hammond B3, blues harmonica, vocals, full symphony orchestra coherence, dynamics, sound stage (see what I mean, really, does any body care what I am hearing???) are all very significantly improved. This is not a subtile thing at all. The realism of Diana Krall in my living room is downright strange.
I don't know about the 'vinyl-like' thing. My vinyl was a long time ago and not all that great. Tons of distortion, as I recall. But I could be very easily convinced that the PC audio solution is all about jitter removal. What I am hearing may, in fact, be due to a severely reduced jitter quotient at several junctures along the electron paths.
Bear in mind however, that I am replacing an unmodded Toshiba 3950 (and more recently, the OPPO DVD player). So, it is true that my previous source was not all that great. However, the Toshiba did replace my Norh CD-1 tube player. I thought the Toshiba was easily at least as good. Also bear in mind that I never heard the SB3 in its raw, un-modded state.
I am still a bit worried that the SB3 problems which everybody seems to be having may eventually hit me. Some of them have already, but I may have been the cause of some of them. (An untested theory is - Don't use the remote to Browse and select tracks from your library if your Web server is also up and running. I think doing that gets the SB3 out of sync with the server, leading to music stoppage. I haven't had any probs as long as I stick to the Web Server as the driver of the show).
So, run, don't walk to PC audio, especially Vinnie's mods for the SB3.
