What are people's opinions on the Parasound Halo A52? Topspeed has been most helpful in mentioning this amp, but I've wondered if anyone's ever used it, and especially with B&W CDM series speakers. I'm seriously considering it, or at least trying it out for a while. The only concern is that it lists a 0.2% THD, which seems a little high, since the non-Halo version (HCA-1205A) only lists 0.03% THD. I'm not sure if at that level it makes much of a difference. Will this measurement affect transients, detail, and microdynamics at all?

Thanks!
