I've been testing this little thing for a while. So far I have driven it: Pyramid Gold 4080 (5" drivers), Acoustic Response "white van specials" (12" drivers), Sony SS-MF550H (8" drivers) and 2 different subwoofers: Sony SA- W2500 (10" amp), Bose AM-5 (two 6.5" passive). My overall assessment is that the DSP built into this little unit is VERY bass heavy even after some serious EQ work and is more noticeable with larger speakers. Subwoofer with crossover and high frequency speaker outputs, it's incredibly balanced even with big stinky drivers like the 12" driver. There's no noticeable difference in sound quality between Bluetooth or Aux in. For the money and size this little amp is impressive if you're willing to tinker with it.
