Krell FPB 300cx or Now?

I haven’t heard the Constellation. IMHO, the only amps I’ve heard that might be clearly better are the Gryphons.  At much higher costs. I can’t imagine what similar maintenance might cost if you had to send it to Denmark. I suggest holding onto the Krell FPB.

Ditto! Hold onto that Krell! At that design level differences are subtle at best!

So far, I like your comments!

Yup, keep it. The FPB was a great design, arguably Dan's last great effort before getting kicked out of his own company. Over the years I went through most of the stereo models, from the original 200 (later 300cx) right up to the 700cx. To my ears and in my system the 300/400cx was the sweet spot of the range, but you can't go wrong either way.

I eventually moved on to Boulder 1060 because I needed a more living room friendly amp, especially in summer. But sonically it was more of a lateral move. Perhaps a bit less bass power traded against a bit more refinement, but indeed subtle differences at best .

So if you can take the heat, stay with the Krell.

I am still staying with the Krell FPB 300cx, in a NYC apt. no less! Just sits as a black burdensome box on a platform, Sphinx-like, stolid . . . and melodious.
