About a month ago I bought a Music Vault Emerald from Sound Science [google soundscience audio] Neal has devised some beautiful PCs expressly for audiophiles. I piked his middle piece because it has very good DAC in its sound card. AB comparison's show up the DAC in my 14K Lexicon preamp. 2TB hd for storage, a second one for mirror back up. Solid state hd for operating. 17" wide fits nicely in rack. Very quiet, except when ripping cds. Runs cool. HDMI out so you can put its video interface anywhere. Cordless keyboard/trackball. Windows IR remote to teach my RF universal. Redbook cd's sound way better than from a transport. Decodes downloaded 24 bit music from HDTracks and WAV copies of hi-res DVD's fm Reference Recordings. Media Monkey will convert anything to MP3 or iTunes, if needed. USB port on front and several in back. Digital out/Anal out, wireless to your network but also enternet ports, so it also replaces my Sonos system since its sound is better. Just takes some work ripping, correcting megadata, setting up favs on internet. If you want your music to sound the way you used to think it should, this is IT. And all the music is instantly accessible. Nirvana.
