Weiss DAC2 or W4S or PWD or Zodiac + or . . .


I'm currently using a Benchmark DAC1 USB fed from fanless, SSD equipped Windows box on a wired network. Playback software is *cringe* iTunes. Music is on a Netgear Ready NAS NV+ in aiff format (but will probably start re-ripping w/DBPoweramp). I'm also playing around with a Cullen Circuits modified Sonos feeding the Benchmark via S/PDIF. I'm using a Crimson 710 pre into Crimson 640E monobloc amps feeding Sonus Faber Cremona Auditor speakers although I may be upgrading those as well.

If I end up with the Weiss I'll probably get a Mac Mini and run something like Amarra. If I go with the PWD I'll try the Bridge. Otherwise I might stick with the PC and try JRiver or something.

So how around it? One of these or something else?

I do have W4S DAC-2 fed async USB from a notebook, Windows 7, running foobar playing FLAC.
Superb sound, absolutely no complaints. Much better than the Benchmark via S/PDIF I used to have before with the same setup. YMMV.
Might also want to consider the Resolution Audio Cantata

Thank you all for the comments.

The Cantata looks interesting but a bit pricey. I did have an Opus 21 CD player a couple year ago and wasn't "in love" with it. It seemed a little polite on music that is less so. I was using it direct into my amps at the time so maybe that had something to do with it.
i love my zodiac+, it sounds very smooth (i think its because of its own clocking chip), and i use it as a preamp, connected directly to threshold 10e monoblock - I Am very happy with the results.

I also have the w4s dac2 for my other set up, so far I think the zodiac+ is in a different league; but maybe i should just let it run in a bit more before comparing the two.
