I use the for more than a year.
The +: it has a good performance for a low power
the -: Bruille fans enough, no protection against dust and clip easily.
j recement have tried the amp with ax jb system 400 but the result is disappointing
pretty good value for money. I've used the almost daily (not thoroughly) and I have never had a problem with.
With the experience I would do not have that choice.
