I recently picked up a 4B3 and find there is nothing it is lacking it's sound. Previous amp was a Classe CA-201 that I liked but the Bryston just sounds all around better IMHO. Rest of system is Canton Vento 890.2 DC, BP25 pre and Teac PD H600 cdp.
You have a nice system there and I recommend you demo a 4b3 if you can.
