Has anyone tried an amp from Class D Audio?

I have the SDS 470 driving the upper frequencies on a system biamped with Bel Canto 1000m reference on the bottom end and they sound fabulous. Speakers are SP Tech rev III, tube preamp EAR 868 .
Enthusiastically endorse the CDA as a bargain of the first order!

Thanks Springbok10 -
I've been using CI D-200s on my Timepiece 3.0s, but I'm considering trying the SDS 470 with them, and moving the CIs to a pair of ATC Passive 20s in my home studio. I've always had a "you get what you pay for" mentality, and the low price of the SDS has made me a bit hesitant. With the return policy, I guess I should just try them out and see. Have you tried out the SDS on the bottom end to see what they could do?

No, Spenceroo, I haven't. I will at some point, just want to break in the cables, etc, as I had to change cables once I bi-amped. I used to have Acoustic Zen Double Barrels, but now that I bi-amp I cant use them, so use Clear Day Double shotgun + Signal ultra, doubled up on each channel- each terminal has a banana and spade:)
Once everything is settled, I will switch the leads and will post my findings.

Hey Spencer
I think you will find the 470's quite pleasing. I have a few of the smaller powered version of these same amps and have been running them for a couple years as they are the platform of our Hybrid power amps.
Just spoke to Tom today about the 470's and will certainly be using these higher power versions as well.
Should have no problem with those Timepieces (nice to know you still have them).
Be well and keep us posted on what you decide to go with. You are welcome to contact me if you want to hear more of my thoughts on them. If you don't still have my email, you can message me through A-gon.

Hello Response34,
Knowing who you are, I feel confident with your confirmation of the 470. I'll have to give it a try. The Timepieces are just silly good. They are the centerpiece of my system, and will be with me till the end. Best audio purchase I've ever made.
