Thanks, Markus for the added suggestions, including Coda. The challenge for me (just a newbie) would be figuring out in the abstract not just whether the preamp/amp would work, but would they work well together and with my speakers. That implies more research, but having these names halves it for me!
I'm taking notes on everything, and am quite happy to see the conversation go wherever. In fact, that's probably the biggest fun for me — to see where folks take this question.
I love this suggestion about 4500 wpc for a bookshelf. It reminds me of that Darwin award about the guy who supposed strapped a JATO jet engine to his car and then disintegrated himself into the side of a rock-face, Roadrunner style.
