the beo lab 5 sounds perfect. from the lowest deeps to the crystal highs it sounds perfect. the midrange is almost alive.It really puts u to the scene.but its really not 2500 watts in fact the bass is 1000 and the mid and treble gets 250 amps each. but really its just worth it. i listen to some jazz n classic it really works. i ve experienced live perfomance from many artists and this thing is a perfect replication. The dynamic range is perfect its not muddy like the usual subs speaker stacks. the bass software is the magic. i have compared with my old revel mark levinson hifi but this is outstanding.just perfect. for the best connect to a mark levinson pre amp the bang pre isnothing interesting just the damn design.
