The OP has GOTO and TAD...that stuff ain't free.

Saw a few 1505s on ebay for ~800 each. GOTO would charge that much for a speaker terminal (half joking--might get a pair for that).

Relatively speakering, 288/1505s are still a bargain and big bang for the bucks compared to import Japanese exotica.

Plus you don't have to worry about beating it with the next experiment to come down the pike. That is my main point.
