Fritz Carbon 7 and tube amp?

more than enough, the primaluna drove BW602 without a problem

Give Fritz a call. He's a great guy and who would know better?

I bought a pair for my son and Fritz said that 100watts was about the right territory to drive his speakers optimally. That really pushes you towards SS, if you don't want to break the bank, not that the speakers would shame a more expensive tube amp at all, they are dam fine speakers, but good tube watts do tend to cost a bit more than SS ones when you get to 100watts.

Thanks for your interest Steve. Any of my models can be driven with your tube amp. Check out the impedance & phase curves of my designs, no other loudspeakers have such smooth curves and are as easy to drive unless they also use series crossovers.
