Sean, I like this good mentioning of "Power Bandwidth" is realy missing parameter that DOES specify how good this amp should sound to make everyone clear that specifications means something at least.
How about amps that have badwidth(and certainly amplitude) limitations truely according to a-must to follow RF compatibility rules and with no compromise to the hobbyist-built components? It realy just a matter of time fine-tuning input, driving and output stages to the perfection and carefully and thoroghly selecting values for correction to prevent any kind of self-oscillation. There are too many tips on amp-building and tuning but the bottom line is that self-oscillation on 200kHz or in the range is NOT acceptible on any component.
Certainly if OpAmp chips are used in input and driving stages the self-oscillation problem is already solved but sound is what will suffer. Tuning transistors or tubes is much more complicated and time consuming issue and time consumption is not good for business.
