I own an ATOLL PR 200 + ATOLL AM 200. The sound is good, but...the reliability is very poor. The unit has only three buttons, but 2 of them already broke . The problem is the soldering of those buttons on the circuit.
The input selector button "clicks" like a the ones on a washing machine.
Another problem is that the units have to be "on" day and night! The "off" switch is meant to be used only when you'r on holidays.They hid it on the rear side. The new SE version finally has a stanby switch on the front side. I have tried the electronic input selector buttons of the newer SE version in a shop and unfortunately they don't have the feel gear in this price range should have. I use the power amp without its cover, if not it heats up to much.

the pr 200 produces a good sound: the weak point is the finish, the weldings of the buttons are too weak. I had to repair them already twice
