Mark, it seems to me you're missing the most important part of the planning effort. We need a floor plan so we can help you decide which other rooms to sacrifice in order to achieve an optimal (or at least not so square) set of dimensions for your listening room.
We LOVE demolition! Sawzall, sledge, bring it! I'll be right over!
What he said.
One other thing -- re: kitchen sink, I'm really glad I went with what most people think is an odd choice, a dual sink with one very large and one tiny side. It's great being able to put any sized pan in there, and the other sink is mostly for dumping your coffee while the first sink is full of water.
Next time I would probably go for one humongous sink and put a cheap plastic tub in the sink for day-to-day dish washing. Doesn't look classy but works better than anything else I have seen.
OK, another other thing. Pull-out sprayers are annoying. Pull-down sprayers are fantastic.
Edit. I like that "before" sink too. It would be nice to have less drain space and more sink space though.
