Logitech Squeezebox Touch DAC: How Good?

Hello All,
I am seeking some technical advise from you all that How to connect (wire less) the SB Touch to DAC? I do agree the touch has DAC still I need to us my external DAC. Please Suggest. Also the possiblity to go with wire less connection between from Laptop/External HardDrivd to SB Touch? My Setup is planned....
External Hard drive>Laptop>SB Touch>DAC>Stereo System and speakers.

Thanks

SmHoll, I've been using the Bryston BDA-1 DAC that I borrowed from Dan.

BTW, yesterday evening we have a major shootout with me, Dan and Brent:
- SB Touch analog outs (Mac server)
- SB Touch digital out to Bryston BDA-1 (Mac server)
- Cary 308T cdp player with tube output stage
- MacBook Pro USB output to Bryston BDA-1 USB input
- MacBook Pro USB to Empirical anti-jitter device to Bryston BDA-1 digital input

Results of the first three were similar to my earlier brief testing. The Touch analog out is very, very satisfying, but the Bryston and Cary are better at isolating images in space, and better at bass control. The Cary seems a touch more "human" (presumably due to the tubes).

Bottom line is that I do NOT feel compelled to get a DAC for the Touch even though this is my high end audio system! And, I don't feel that getting a DAC would be a waste so I might do that in coming months.

Caveat: interconnects are RCA Cardas Golden Reference, which, as many of you know, have a nice musical touch of their own.

BTW, much of the testing was done blind. As in, blindfolded!

ALSO,

Mac to Bryston USB input sounded distorted!
Mac to Empircal anti-jitter device to Bryston digital input was fantastic.

Finally, today I called Squeezebox support and they are well aware of the two problems I along with others been having:
- USB drives directly connected to the Touch. They are working on this and are hopeful that it will be a software fix.
- Player on the Mac working intermittently (I find the server works great, rock solid, but player often can't find the Touch to control it.)

Overall happy camper.

Art, in these listening tests how did the Touch digital out compare to the stock 308T and MacBook->Empirical->BDA-1?

On first listen is is hard to find any differences at all! After a few minutes though, it becomes clear that the Touch is very enjoyable, and does not have any serious flaws that make it harsh or uninviting but compare to 308T and Bryston/Empirical, it has (a) somewhat looser bass and (b) flatter presentation. Both the 308T and the Empirical-Bryston would place a singer or instrument more clearly in space horizontally and vertically and have a bit more depth of field. Also they had a bit better bass control. The 308T seemed extremely similar to the Empirical Bryston at first but over time there was a lifelike quality, very subtle, that tubes often have over solid state.

I suspect that playing the Touch without direct A/B to other sources I'll end up just enjoying it.

BTW, I forgot to mention that we also tested my Devilsound briefly. In a high end setup it sounds very vague and ill-defined compared to the others, and it is particularly less detailed and refinced than the Touch. However it does haver its own cabling and so does not benefit from the Cardas Golden Ref. I will continue to use the Devilsound in my home office.

Just received my touch today and thought I'd share my initial thoughts. Setup was a breeze. It connected to my wireless network without a problem and I was able to access my computer/server that is also connected wireless. Flac files, 24/96 WAVE files and even a 24/192 rip of an Eagles DVD-A played flawlessly without any stutters or rebuffering (again, this is all over a wi-fi connection).

I connected the touch analog to my preamp (Wyred4Sound STP) and coax to a DAC (stock PS Audio DL3) and switched inputs back and forth on my preamp. There is no lag when switching between the two inputs, but there is a difference in volume levels between the analog outs on the Touch and the balanced outputs on the PS Audio. I tried to adjust the volume a few steps down when switching to the PS Audio to match the levels as close as possible when switching between inputs. I know, not very scientific.

My initial impression is I won't be selling my dac anytime soon except maybe to upgrade. I could definitely tell a difference between the analog outs and digital into a dac. Without getting into the typical audio review adjectives to describe the differences, let's just say it brought me into the music more. It was subtle, but noticeable even if I played the volume through the dac at a lower volume than the analog outs. The analog and digital outs on the Touch do sound better than the Duet it replaced.

I was hoping to sell the dac and to simplify my system with less components and cables, but I can't do that now that I've heard it through the dac. Regardless, I am happy with the purchase and will continue to see if there is any change in the analog outputs with time.
