In a few years I bought 12 pieces of this model and almost the same amount of other TSA amps series. There is no other to say than that you just can't buy other new amp with parameters like this in the same price.

Very high power, very low weight, interior good designed and made. Properly often cleaned with compressed air it will handle hard work in dust of openairs and fests. Here I must say that the device is completely trouble-free. It is true that I had to return one amp which just after taking it out of the box did not want to turn on, but with a guarantee in the Thomann there are no problems, so it was nothing to worry about. The rest of the amplifiers I have purchased work very well until now. What's more, there are no problems with using elements. After few years the fans do not get damaged and the potentiometers do not creak. To make the product even better, engineers should add a XLR male on the rear panel to be able to output the signal. My dream would be the bridge function at 4 Ohm. Overall, the amplifiers perform very very well. Mine works under constant heavy load in the bass. You can look for stronger amplifiers, eg Chinese copies of FP100000Q but they are twice as expensive and you can forget the warranty. I think that these amps are real workhorses, and at their price they are unmatched even today!
