agreed. it was hard to hear much of a difference between my magni and my wa7 with the pm-1. my previous two cans (only ones I've used with both amps) the difference was easily detectable.
something designed for high efficiency/low impedence would be best imo. I had very little room for volume adjustment before it became too loud. around 7-8 o clock on my amps was already loud.
