I had sr80 and it was simply fun, but screechy high with tighter bass than sr60.
I heard sr60 and sr125 and they were also good in their performance vs. value.
Now I just got sr225 and it has electrifying guitar and slamming drum sound.
Simply I feel like I'm in the center stage.
Alessandro MS1 is hard to beat in price/value category.
umm, arnt the a500's and a900's too balanced to be able to rock out to them? i dont know much about this..but hopefully iron_dreamer will be able to clear this out. Well, i would be able to too in like 2 weeks when my a900's come.
