Accuphase or Leben for heavy metal

Neither, Accuphase or Leben for heavy metal. I suggest SPL from Germany. Their demo at AXPONA was impressive on all genre of music. 
 

@apanhc Just so you know, there's no way to design an amplifier (or loudspeaker) for a certain genre of music. As long as you have the bandwidth and power to reproduce the signal at a lifelike level you're golden, as long as the electronics and speakers actually sound like music (rather than electronics) while doing their job.

If you like to play loud, you might consider more efficient speakers. For example if your speakers were 96dB instead, you'd only need 1/4th the amplifier power to make the same sound pressure and quite often you get greater dynamic contrast and greater detail at the same time.

The greater dynamic contrast has to do with less thermal compression in the voice coils that you get with higher efficiency drivers. The greater detail often has to do with the efficiency as well, since the drivers are often faster.

I like the Accuphase. 
Great detail for some Heavy metal guitar licks.

I agree! 😎

What speakers do you intend to drive?
