Honestly, i wasn't expecting much for this price, but I was in need of a small monitor amp, and when i got to use it for the first time, i was pleasantly surprised to say the least.
Right out of the box, I saw that it is made like a tank, the frame is all metal, and it is quite thick, in some places (like rack ears) it's up to about 3-4mm.
About the sound quality, well for the price, I was expecting way less. Of course it's not a class A amp, or anything similar but as a class H amp, that costs this little and has the capability of hundreds of watts, it sounds surprisingly well. The highs are a bit granny, and the lows are not as powerful as higher end amps, but the middle frequencies are crystal clear, there fore currently it's powering the mids in my current PA rig.
What surprised me also, is that the power ratings are true, and this amp is definitely capable of putting out around 800W at 4ohms bridged.
5 stars from me.
