Dolfan, I would think your statement(s) might be right. I listen to my maggies between 62-78dB SPL. And maggies DO SUBTRACT low level detail at modest sound pressure levels. (less than 80dBSPL, or is it more like 85dB SPL?) In another thread Tim (tireguy) reports that he listens at about 87. He had mentioned a suggested value of 700W of tube. Give the 9 dB difference (assuming similar listening room size and listening difference [I can only guess that his room is likely bigger than mine], and assuming maggie SPL output is linear with respect to power input [i.e., no thermal compression, etc], then P=2^(dB/3), P=2^(9/3), P=8:1. So one might expect that I would need 8 times less power that he cites. 700/8=90wpc to one sig fig. Which is that power amp I'm using (90wpc with kt88 tubes, a little more than 100wpc or so with my kt90 tubes). So the SPL differences might explain why I am satisfied. Though it's likely psychoacoustical, since I don't like the sound of sand amps in my budget range, and this was the biggest tube amp I could afford at the time.
Although, I do agree that maggies sound best (at least my stock ones, with the poor quality passive parts) at >80dB SPL. But the music sounds louder than life and not as natural (to me) at those levels. It sound great at those levels, just not natural. But I do hear I'm missing some detail and magic at the lower levels! Some day I will be able to budget those mods. I probably need to address the room more as well.
Great thread eldartford. and Tim, I guess I need to borrow a world class +700wpc amp! Or whatever callibre of amp needed to surpass my 90wpc tube amps!
