I don't know if I've ever heard someone say something negative about that amp. I do know that the Memphis Hybrid, the amp that "replaced" the Belle isn't as good. My next amp will most likely be a Belle, especially because they're pretty cheap on eBay.
i just ordered the hifonics bxi60-4+1k . almost as powerful as the belle and only $360. if this amp does well i think i may have to rate it over the belle due to the active capabilities and the fact that its so much cheaper than the belle which averages at least $800.
