I can only comment on my experience with some chrome bumper 32.5/BD160/Hi cap. I added a teddy cap later and some after market cards. Great toe tapping sound but i feel it does come at a cost. I think that mid bass hump that gives that forward presentation actually masks a hell of alot of what's happening on the record or cd, and whilst you get that in the room feeling with naim for me it actually lacks emotion and timbre. I now run a system that still has a bounce but oozes musicality and detail. I still have my old Naim set up and will probably give it to my son.
