I did not use a long time because I did not like at all the sound coming out of a sub use.

The amp does not follow at all in complex loads, it must glean the equalo to have a little something and there, the huge excess of power becomes a little help.

A bit like using a 1 "compression to 200 Hz ..

is super light, that it must be acknowledged. It is close to 1.3 kilograms per kilowatt amp. It is the only huge interest in this amp. A if the current widespread use.

Against by using top, or broadband, which does not drop too much, it's all good.
