bermart,
I have a 4Bsst2 and am still using a BP6. I agree with soix - -effectively, it's a straight wire with gain. Remember, as soix pointed out, the BP6 shares very similar topology with the BP26 (as per James Tanner) For a CD spinner, I recently added a Bryston BCD-3 for an extensive collection of RedBook CDs. Driving a pair of Thiel 2.7s and a Thiel SS2.2 sub, I couldn't be happier with the BP6 and 4B amp.
