I know my tfm may need a tweek, but I will guarantee it's not far from spec. It took me an hour to even notice the issue. Of any amp to be accused of coloring the sound, Bryston is the last I'd expect. I have absolutely nothing against Carver power, I just calls as I hears 'em and the Bryston stomped the tfm and slightly edged out my Hafler. As much as I love a good debate, I think Tom could put a stomp on this one. Tom, seeing as you have gobs of Carver experience, take the 4b vs a tfm... let's say 35... This is a comparison based on the pleasurability of the listening experience.
