It ain't perfect, but it does me very well.
Computer for music source, sent via balanced connections out of an M audio 192 audiophile to Carver PM 350, then to russound 4 way 2 input speaker switcher(with impedence protection switched off) to infinity Crescendos 3009. Balanced connection also patched through to the Rotel RB 1080 ST and on to Maggie 1.6 QRs. An unbalanced signal is also directly sent to apt holman Preamp- > Carver M 1.5t, and then on to all the rest of the speakers via Russound 12 way autoformer a/b speaker switcher.
Computer for movie source, sent via unbalanced connections out of another M-audio 192 audiophile to adcom GFP 345->adcom GFA 5300 -> russound 4 way 2 input speaker switcher to NHT 1.1 and Infinity reference 525's (and sometimes to the crescendos or vice versa) An unbalanced line level signal is also patched through to the apt-holman, so 'all the other' speakers can play movie sounds if I want them to.
My truck has a totally 'ghetto' system that sounds very good to my ears, one of those Lepai 4 channel output chip amps, that has usb and sdcard input, sent to a pair of Bose 151 outdoor speakers, (that I frequently throw out the back window into the bed so I have music outdoors) and a pair of Boston Acoustics hd 5 speakers. Sound is great! worlds better then the stock head unit and speakers, (po took out the stock infinity's and put in craptacular pioneer speakers, I just don't care to tear out/re-install a system, so this'll do)
the 'old' computer system, (now that I've built this machine I'm typing on, for movies,) is more and more dis-used, I'll eventually take it down i expect, but for now it's my movie server, and my user interface for my music, but it also has a unbalanced connections from a sound blaster Audigy feeding a Carver TFM-15 directly into a pair of NHT super ones, for the odd time I'm in front of it, and want to watch a youtube or whatnot video.
the 'other' speakers currently consist of
Canton Fonum 200 upstairs in me bedroom.
B&W forgotthenname bookshelves, (in the shed)
KLH 3 way outdoor speakers (in bathroom)
Advent 3 way outdoor speakers (in backyard for pool music)
I also have a pair of von schweikert odd bipole/monopole surround speakers sitting idle, and
Infinity Qa's sitting Idle
Living like a king, I tell you! I'm pretty damn happy with my system(s)
(edit to add) quality of recording is very, very interesting how different different recordings sound. for example, many of the live soundboard dead recordings (bootlegs) have an actual palpable 'presence' that belies the fact that they are high bitrate MP3's, I mean, it actually sounds like I'm at a live dead show, Phils bass sounds like a bass being played live, not recorded in a studio, mickey and bill's drums sound like real drums, the kick drum,,, Kicks. While other soundboard recordings are only 'meh' and have no soundstage or presence or anything.
and, crap recordings, that are victims of the 'loudness wars' really are obvious. "Hurt", sung by Jonny cash is a perfect example... it doesn't sound bad so much as fatiguing, at least until that final crescendo at the end, where it gets totally jagged and sounds craptacular due to the massive clipping/compression in the original master... while on the same system, Emmy lou Harris's version of 'Wrecking ball" from her album 'Wrecking ball" you can clearly hear all the reverb and her voice just makes you melt (or should I say grate) into... while the kick drums are totally flabby and sloppy sounding, (but I love it)
I really enjoy the differences in recordings quality now, and just accept them for what they are, rather then hating because of this or that flaw.
Hoppy New Beer, everyone.
