«  an amplifier that provides »

I use this amp since March 2011, I have not tried other amp in this range there. However I have chosen following the advice of a friend, who tried several amp whatsoever Lab Gruppen amplifiers or other high-end. And in fact this amp is great, its power does not decrease after several hours of use. it remains dynamic and does not heat, and even under 2ohms the power is there.

lowest body weight 35 kilos.

level value for money: excellent
this choice I would do without hesitation.
