Peachtree Decco 2 setup...

I would question where and how you have the speakers set up. As mentioned by Hotmailjbc, are they in phase? How close to walls, etc...
You can test the digital part by hooking up the cd with rca cables to the decc0 to compare? Also, tubes do get old. Have you had it checked? Supposedly, the tube can be bypassed.
Final question: Have you compared your pc audio vs using a real cd? Is there a difference?
From what I've read, the Decco amp is designed for smaller speakers and doesn't have a ton of power. You could always try an external amp to see if the amp section is your problem.

I would suspect a poor speaker/amp match just because all the Dynaudios I know like lots of juice. From what I've heard or been told, SimAudio amps like them, so do KT88-based tube amps.

That said, positioning and the room make a great difference in how speakers sound. More hard than soft surfaces tend to make the music sound, well, hard. Positioning near the wall or too close to a corner can make boom.

If you suspect your DVD player is the weak link, cheap tweaks include a power cord, an isolation transformer (eBay) and antivibration footers like the ones from Herbie's Audio Labs. The PC source can be helped with a quality USB cable like the one from Acreyes here.

Also, is your digital interconnect 1.5 meters long?

Can you bring your main system's integrated amp and try that in place of the Decco? If so, do that without changing the speaker positioning. If it sounds equally crap, you know it's not the Decco.

If the integrated fixes the problems, it may be you don't like the DAC section of the Decco or it's not driving the Dyns well enough.

If the integrated fixes problems, try using the Decco as a preamp/DAC with the integrated as a power amp.

Experimentation should tell you what you need to know. All it costs is a bit of time and effort. I don't have a Decco, so I'm not defending it nor am I blaming it.

Chubz71,

The other posters having given good advice, especially swapping out another amp and seeing if it too sounds bad.

I had the first gen. Decco for a three day audition in my system about a month ago. I used a Tara Lab digital cable to use my NAD c542 cdp as a transport. I also use Analysis Plus Oval 9 speaker wire. And I used my NAD 320BEE to compare.

I had similar impressions as you. It sounded just as you described. I did prefer the sound with my cdp connected directly to the amp section by rca jacks. And when I used the NAD as a transport I preferred it not using the tube section of the Peachtree. The tube section imparted a bright forwardness to the sound which completely threw me as I never expected that from a tube stage.

When using the Peachtree DAC there was definitely more detail but the music lost much of its weight, presence and body. I was very disappointed because I really wanted the Decco. When putting the NAD 320BEE back in the musics fullness was restored.

I believe it is a great piece of equipment. It's beautifully built too. And I can see why people love it. I just wanted to post my impressions for you because maybe you and I just came across a compatibility issue in our systems and thought you might be a bit relieved that you are not alone. Sometimes things just don't work out.

Cheers,

Scott

I haven't heard the Decco, but I doubt it has the juice to drive *any* Dyns. I had Excite X12s (easier to drive than your Audience 42s) and my Nait 5i didn't have enough to open them up.
