I possde this amp for 1 year, I bought from a group of varieties with returns JBL 250W RMS.Ce group had for over 5 years and I can say that a strong tape.
The amp is not only in teuf for 10 hours with no minimum cut out t winter and never really seems dconn.Il trs robust!
I found him a ngatif point, it is dpourvu output to rebalance the signal on a different amp.
I do not know the original price but for the price I pay ke (400euros) I'm ke SATIF.
