I have directly compared Parasound (HCA2205at - which I still have), and the B&K Reference 200 and MCA (I think) versions. I am driving NHT 2.9's which are very current hungry, and the Parasound was a better match. Better bass extension and control, but also a bit boomier, if you are not carefull with your speaker placement. I also agree the B&K had a very neutral sound, but it was just too laid back for my taste. After living with both for over a month, I kept the Parasound.
Hope this helps!
