I use it for a year and a half in HD15 4 to amplify kappa 15LF, it does not heat up hardly clip, features a silent fan trs, a serious building, and a power torodale Large Diameter.
Goodies: solidity, reliability, Raport qualities capacity / price, its relatively neutral (for this price range), conections complete the grid in front of the anti poussirre between air (I opened it after a year it almost like new silent yet he dusts for the PRS).
Cons: No Crant to stop for the XLR inputs, fish of around 20 Killos.
For me the top of the amp low cost. I repeat no one line shells and I put 9 because it saved my bank account.
