Amp for harder music with lots of sounds.

I'd consider bryston ( used or new ) . exc. all around amps with plenty of balls and a great guarantee......

There are pleny of amps that fit this bill.

BTW- all amplifiers that have any guts playing classical will work fine for death metal and electronia as well. Issues of power delivery into load, bandwidth and distortion really do not care what kind of music you play!

FWIW you might consider tube amplifiers as well- there are plenty that fit the bill, and as a manufacturer I can tell you that we play plenty of stuff across the spectrum. I don't think any manufacturer is going to limit themselves to female vocals and light jazz!

Most any SS amp with around 150 WPC should be enough. Those small woofers probably can't take a lot more power than that without sounding overly distorted or risking a failure.

PMC use Bryston for their active versions...why not go for Bryston...
