I agree with the prior comments: if you want to keep the speakers (and they are good in the right set-up) then a tube amp, which combines the best of both the world of valves and solid state, may be the best solution and one that will accommodtae changes to you speakers in the future. As I noted in a response to another forum inquiry, I have the Octave MRE 220 mono's. In a word they are "incredible". Octave integrateds may be a lower price option that would deliver a seemless solution at the front end as well. You can always add the "Black Box" if you later decide to increase the capacitance of the power supply to drive more difficult loads.
