I agree with those above.
The Leben sounds like a simply elegant amp I would love to own and play string quartets and traditional jazz.
Accuphase or Leben for heavy metal
Guys, I have a short and practical question. I have an opportunity to buy either Accuphase E600 or Leben CS600X at good price. I listen to a wide range of music, but particularly interested in which if these two amps is better for heavy metal particularly. Under all other equal conditions, speakers are easy to drive 90db Piega at the moment. Maybe none of these two, which is also an option.
