It's been three years since I use this amp and it works just as well (hopefully!)
I like his "disign" and that simplicity of operation (like all amps remark!)
However I find quite big weight (14kg) and I also find that the connections for pregnant n'écéssitent son to tighten the red and black terminals are no longer so necessary haujourd'hui because most of us SPEAKON use connections to wire the speakers so I use personally SPEAKON connections (although that is a detail!).
There is also a breakdown that makes some noise when I have the opportunity to participate in the sound and theatrical lighting parts (but what you want is technology that does that!)
It is actually the first I bought and I'm pretty happy.
The price / quality ratio is not all bad for this range of amps INTER-M because it can be found on the internet today nine with a value of € 300 at the time when I had bought store a value of € 460 and I think today it should be € 360.
I think I would do gladly that choice now because the price of it down to but not now well ventilation and that's a shame!
