Class D amps?


Are there any Class D amps today that avoid the pit falls of the older Class D amps? ie: roll off of the top end for one.

Hifial, my only concern is that it puts out like 700 watts into 4 ohms. I have 93db speakers.
I thought my Bel Canto REF1000s were the best bang for the buck. They were upgradeable from MkI to MkII specs which really really brought out the best of the sound.

I've since upgraded from the REF1000Ms to a pair of Electrocompaniet Nemos but I can tell you, the incremental improvement isn't a lot more than the difference in price tag would suggest.

I did find they could sound a bit lean and the depth of the soundstage wasn't as deep compared to more expensive amps but you could improve that with a good tube preamp. I have had great success pairing the Bel Cantos with Ayon CD5S (tube pre, CDP and DAC in one box) as well as an ARC Reference 5 (then 5SE).
Here are some from "Arion Audio" is a USA based company producing class D amplifiers.

Seadog1,

The TBI Millenia MG3 is 35 wpc and is designed for speakers that are easy to drive. The guys over on Audio Circle are raving about it and the cost is only $500.00.

I am not associated in any way to the product but when I get my new speakers I am going to give it a try.
Not an issue. They play nice with all types. Watts are just one aspect and not the end all. There is a misconception that you can have too much watts. The overall measurements on the Veritas NC1200 is about (some are the best) the best you can get.Go to Merrillaudio.net and call Merrill and discuss any concerns or tech questions you have. Merrill is very conservative and will be very upfront with you if there is anything to be concerned about.
Let me know after you have a chance to talk to him.
