Swede, believe it or not my 380 is surprisingly very dynamic. I have only been playing it 2 days and it went through a few changes. At first listen the bass was so strong one of my speakers popped. The next day, after a few hours, the bass was so anemic and the sound got bright. I thought of selling it. I left it on for 24 hours and lo and behold, everything came together.
I also was thinking of buying e Diablo 300, never head anything bad about it. I am using my Accuphase with Kef LS50 metas and I never know these thing could sound like floor standing speakers in my room. I have only had my Pass 250 less than a year and have not used it much. I am surprise the E800 was polite sounding. When I feel my 380 is good and broken in, I will be curious to hear how the Pass sound in comparison. I use Dynaudio special 40’s with my Pass and that combination throws a HUGE soundstage. Once I recover from my purchase of the 380 and Diablo will be next on my list.
