I have the iconic Krell FPB 300cx, purchased new in 2001. It’s a Class A amp and does an excellent job driving my Dyanudio Confidence C2 speakers. The sound is glorious and while I’m not looking to make a move today, I AM looking to at some near future point consider a new , more powerful amp as my speakers can take anything I throw at them. My new home has a larger room so I’d benefit from more raw power, so I have my sights set on the big brother Bryston - the 14B3. With that said, I auditioned the 4B3 and the dealer happened to ALSO be a Dyanudio dealer and got to listen to this 4B3 with my exact same speakers and a preamp not as good as my Krell Foundation. There was no sub bass in the demo, while I have a large Rel sub bass in my system. To Beysron’s credit, I have to say I was more than a little impressed. The Bryston sounded virtually as good as my Krell. 300wpc v 300wpc and if my capacitors all burned out tomorrow I wouldn’t hesitate at all to purchase the 14B3. Sonically the two should sound the same with of course the primary difference being in power and headroom. But the sonic properties virtually identical. Always best to audition if possible. I imagine there must be a Bryston dealer in your area for an audition?
