Thanks for the links. I hope everyone reads the first link. It was interesting to see that many of the expensive, often lauded caps are in class D.
As with cables and powercords the claims are astounding. That audiophiles would rather discuss this and that capacitor rather than drivers, crossovers and multi-amplification is astounding also.
The first is relatively easy to do and supports the American way: "Throw more money at it and it will be better".
The second is far more rewarding and can often be implemented for far less than the cost of a few capacitors or an expensive power cord or expensive cables.
I imagine I am going to get a lot of flack for this.... Just be nice about it, OK?
