Like everything else, it depends on the design, some classD amps are a lot better than others.
Hypex can drive hard loads pretty easy, measurements are also very impressive

Some people accuse them of being tiring to listen to yet others say they are just accurate, personal choice I guess

No, it offers the worst of any technology, in my view.

Some great thoughts guys. If anyone ever buys the A30 ( eventually) I can see my at least trying some of the smaller hypex modules, possibly with a beresford DAC - I think I am right in saying the latter has a variable output?- thereby changing two bits at once. I have sensitive speakers so power is not an issue anyway.

My manufacturing colleague does a class D amp. I got a sample or two but I am not convinced that Tripath chip is all it is claimed to be. The sound from that 2024 chip doesn't sound quite right somehow.

Every amp toplogy has flaws, its finding one you can live with

Colloms views are clear to see: http://www.hificritic.com/downloads/Class-D.pdf

The actual full article goes way deep, many pages. It is worth buying the back copy for evaluating any system. I was asked to talk to Martin Colloms by the UK importer of NuForce. I have to say, I believe he is right. At first listen Class D seems to have extraordinarily huge grip and control, but then after a couple of days, you realise all is not well in 'the land of 70khz' ...........
