Thanks for the Boxplots! I'll check my home e-mail for them. Given the efficiency, it looks like I could go the cheap rout and use the PMY1555 and still get good result (assuming that Pyle's specs are correct). I don't need the high power handling capacity and I could use the money I saved on air-core inductors, polypropylene caps and good non-inductive resistors. There are not that many parts; I might as well use good stuff. I have used expensive wire in the past (when I got it free because I worked in a high-end stereo store) but good quality twisted pair 18 gauge solid core copper wire seems to work fine (as well or better) for me as long as I don't make it too long.

With regard to speakers, it amazes me what a better value pro gear seems to be. Its more rugged, presents easier loads, has lower distortion, is more linear, handles more power, is more efficient, has a wider bandwidth and is cheaper. When you spend more money for JBL, the specs are incredible (so is the sound). Actually, it was hearing some JBL speakers that first made me realize that I should be looking at pro speakers. I couldn't get over the clean dynamics.

Thanks,

Dave
