I'll say a little more - Danny's designs are deceptive. You think that they are built to a budget, and thus will err on the side of 'musical' and that is not actually the case.
His designs (regardless of price) are all pretty much dead on neutral and highly transparent. They sound good with budget gear, but scale up extraordinarily well with more refined amps and front end electronics. Which is why they mate so amazingly well with good tube gear. Because of their easy load, neutral but lively sound, and incredible transparency, you hear everything.
His designs are NOT analytical sounding, but they aren't warm sounding either (IME). Which means a nice little class D amp can sound very good. But it will still be bested by quality tubes or quality class A SS amps.
Part of that is personal taste, too. I've never heard a class D amp I've liked better than even a moderately good SS amp, and of course you know that I'm a big time tube lover so even the best SS isn't as good as moderately good tubes IMO. The problem with tubes is that they just don't sound good on difficult to drive speakers. And that's why I am such a fan of Danny's designs, they allow you to hear with a good tube amp is actually capable of.
