I think most will probably recommend first choosing a power amp that best matches the speaker's characteristics and then pick a preamp that has the best synergy with the amplifier. The size of the room and the listening volumes also play into the decision, in my opinion. I've not heard your speakers but the specs, particularly the impedance characteristics, seem to suggest that they would benefit from a moderately high powered solid state amplifier to show their potential.
How to select and pair a preamp and power amp?
I'm considering returning to a pre/power configuration after years of using a tube integrated amp. I will likely buy used and my budget is $5K. I have Focal Be 1038 speakers, they are efficient but do benefit from power. So what makes better sense, finding the preamp first or the power amp first. I'm at the mercy of the used market, timing might dictate the whole process. Also, any suggestions of tube/SS pairings with proven synergy?
