Yes, the 8008bb definitely has a lot of drive -- it’s a high current amp and has no problem driving a wide variety of speakers. I have not directly heard the Parasound, but I have heard many on this forum describe the characteristics. I have moved on to Emotiva monoblock amps myself, but that’s where I’m at. The stock Emotiva’s are very fast and nice, but just a tinch on the cold side -- upgrading the fuse to an Isoclean really helped and now it’s like a fast/engaging version of 8008. I would say the Emotiva amps (when fuse modified) are worth much more then what you spend on them, but there is definitely a perception that they are "cheaper" and not as good. I run 6 individual monoblocks in a home theater system, and it would be insane to buy Parasound/Pass monoblocks for this many channels, so Emotiva is what I ended up with. In reality, I suspect the Parasound Halo amps will sound sweeter than the Emotiva amps -- the Pass Labs "Class AB" amps are probably the superior amps all around. Please read the following thread on a huge amount of individual amp descriptions.

I recommended the Parasound A21 as a stereo amp upgrade from your 8008bb stereo (dual-mono), but JC1 monoblocks would be better (and much more expensive, lol). Based on the above thread, the Pass 250.5 would be better than JC1’s anyways.
