My previous amplifier was a tube amp. But I burned something out (not a tube, I checked those) and I needed something that was less complicated than my old set up. My old set up was a tube amp for my front Klipches and a Class D amp for the back ones. I also have a 400 watt subwoofer. I used to feed those amps from my computer, which outputs to a discrete DAC. This is for my 10x10 home office, by the way. So I know it's overkill. So anyway - I got the MAMP5 and used 4 channels to bi-amp my front Klipches (these are the ones you can do that on). Then I just did normal 2 channel to the back. I used pre-out to go to my sub. Then I messed around with levels and stuff on the amp and on my sub. Those blue dials on the amp - don't turn them up past about 12 o'clock. Use the little black one on the bottom right to control overall level. The blue dials are just to set "ratio." And you keep them at less than 12 because you want to leave some headroom for loud things in your music. If you hear the fan - that's because you did something wrong. For example, I can make the fan come on by turning the blue knobs to almost zero, then cranking the main volume knob. Because the blue knobs are near zero, there's almost no sound coming from the amp. But it's still working hard. That's because I think the blue knobs basically just work like resisters and the black knob controls the actual amplifier. SO - put the blue knobs near 12 o'clock and the little knob at 9, or 12 if you want loud loud. I think if you turn the bass or treble up too high, that will also trigger the fans prematurely. So it you hear the fan, mess around with the volume & tone knobs. So what does it sound like? My original major in college was audio recording engineer, I used to do sound in a club, and I have done it for live bands, so I think I have decent ears. 1) It's "trebly" - so turn down the treble. This could also be me going from tube to solid state. Either way, turn the treble down a little. 2) bass needs to be turned up a little. 3) Soundstage is good. Instruments and voices appear in 3D space about like I would expect. 4) It doesn't sound grainy. That was my big worry. 5) It's loud AF! If you adjust it right - you actually are getting 50 clean watts per channel. So with me biamping the fronts, I am getting 100 watts to each of those and 50 to each of the rears. These are efficient speakers and I can drive them to earsplitting level with almost no distortion. 6) The remote works, but only controls volume for the bluetooth, USB and card reader and FM inputs. It won't control volume for aux or anything else that is plugged into the back with RCAs. 7) When it does distort, it distorts the way that you would expect from a class-D (I don't think it's A/B for this price). So it's like clean, clean, clean, then holy moly. It's not linear. The fact they put in a loud fan and super ventilated the case tells me this is primarily intended for something like a retail store or a bar. My impression is that it won't prematurely fail. I think it's worth the money.
