I was just sharing this Rotel stuff vs. ADA with my eng homies. How times have changed. The ADA is so much simpler, more elegant in its design and execution. BTW, I've tried to kill my 1000 by abusing its outputs and have not been able to do so.
Actually I thought the opposite ... this is the simpler amp in that all the components are discrete (except for the op-amp and the speaker protection IC). You can really see how the thing works. Its very testable making it an easy piece to fix.
I have not looked at the ADA but I'm sure all the complexities are in the chips. Simpler in number of components more complex in understanding how it works. Most engineers just following the reference design and read up on each chip to attempt to understand what pin does what. Often the chip internals are a complete mystery, maybe you get a block diagram, although sometimes they give you the internal (simplified?) circuit (which usually is not that simple). Just MHO ...
