Unfortunately, the overall volume produced by this amplifier is underwhelming. I connected it with a (real) tube pre-amp which was pushing quite a lot but it just does not feel that it gives 100W at a 2x12, 8ohm cabinet. I really needed to boost the volume all the way up to start getting some actual punchiness and physicality of sound - goodbye headroom, obviously.
To be fair, there are some positives: it is well-built for sure. Also, very responsive EQ. Still, since I bought it to get loud(er) volume, I am afraid it will be going back to Thomann.
Speaking of which, as always excellent delivery service.
