Has anyone tried this amp & D/A? How does it sound? What source are you using? What speakers? Headhones?
I've only heard it at shows, but I'm hoping to get one for review after CES - actually the new higher output version (it has a new name that eludes me right now). It also has a newer digital front end as well.

I have been using this integrated amp/DAC as a second system in my home office for a year now and I love it. I purchased everything from Walter Leiderman from Underwood Hi-Fi, who advised me on building this modest system to get the best bang for my buck. I think the sound is wonderful. The DAC's 16-bit/44.1 chip with no filters or upsampling keeps the music from all my digital files sounding very organic, balanced and coherent, with a nice open top end and a decent amount of taut bass for my monitors' size. Midrange is warm and very engaging. Vocals and acoustic guitars sound amazing. I play everything from rock to folk, reggae to electronica, with a bit of classic jazz thrown in for good measure. No classical to speak of. I'm guessing the tube in the front end contributes to this unit sounding so natural as well.
I am using my 17" MacBook Pro w/2TB NAS containing 30,000+ AIF files as my source. I'm connected to the Decco via a 25' run of USB Booster to CAT5 cable to USB and my speakers are ERA D5 monitors on Target stands. Speaker wire is 8' pair of Paul Speltz anti-cables that were affordably priced and sound great. I'm using a after-market Nordost power cord for the unit which has also made a positive difference in the unit's sound - less restricted is the best way I can put it.
I have yet to try the headphone jack but that will be changing soon as I plan to pick up a pair of Grado GS1000's in January, or a modified pair of AKG 702's.
I'll probably upgrade to the newest version, the NOVA, when it becomes available in 2009, as it is 80Wpc, as opposed to the Decco's 50Wpc. Not that 50Wpc hasn't been enough for the ERA D5's but I'm interested in moving my Usher Be-718's into my office and think they could probably benefit from the extra 30Wpc.
