I have used, there are a lot of years over 20 years !!!!.
it really was tough, with real watts, however at the time (mid 80) this amp worth in 7000 frs .. (1100euros) for 2x225watts.
nothing to do with the power of the last years of exixtence brand, actually made in China.
This was due to power made in France, the brand also equipped with many clubs in France and Navarre ..... so totally unjustified comparisons with boost, pad and I do not know what else.
I forgot the default ...... surely the weight !!!!!!.
