Best Pre-Amp/Amp for Focal JMLab electra 920

Thanks everyone, these are very helpful!

I tried to look for some amp, recently found MacIntosh MC-7300 + C-37 (yes, very old products), and Classe Pre-amp + mono blocks (maybe not the high-end ones, but something like a pair of low ends), not sure what will be the best choice.

I will explore more with the other options that you suggested.

Also, I am also very much into the idea of tubes, since the 920s are a little bit "hard" to me, I listen mostly to classical, with a little bit everything else. The hardness sometimes is killing me. Therefore I think tube might be sweet to solve that.
However, I am kind worry that fist tubes are not powerful enough to push these babies, and second, I heard that tubes will trim the hi and low end that will make the speakers colorles. Will you think so based on your experiences?

Thanks.

Tube amps with 920s won't work well IMO. They are too tough a load unless you only listen at low volumes. I can't think of a good tube amp, moderately priced, that will control those big woofers well.

The 926s have a lot less treble than the 920s and cannot be equated.

The reason I suggested McIntosh SS is because the 920s are a little hard. I personally don't recommend the old McIntoshes you are looking at. Go with the Classe instead although you should steer clear of the CAM200 and CAM350 monoblocks. These amplifiers have more top end than any other CLasse I have heard and that won't work well with 920s either. Try a Classe CA200 instead. All the Classe preamps are very nice. These are my recommendations.

Based on the fact that you purchased the speakers used (or demos?), I ascertain that cost may be a concern. Although I haven't used them (yet), I read something about an Odyssey Stratos working very well with some JM lab speakers, though the actual article and speaker model escapes me. At any rate, if Odyssey amps are as good as users/reviewers describe, they may be an affordable option for you.

I have no affiliation, but with prices and marketing practices such as they are, I am hoping sonically competitive, affordable alternatives exist, are discovered and embraced by those that cannot afford the excellent, but very expensive brands.

Everyone's guess is right, I bought these speakers used, but still considering them as their MSRP, therefore I am thinking of matching them with some used amps that has an matching original price.

Keep that in mind, what will be my best shot? Thanks.

Price is not necessarily indicative of sound quality or , more importantly , synergy . You would do better to just state a dollar amount as some here may not know what your speakers originally sold for years ago .

Some of today's newer tube amp designs are trying to incorperate the plus's of SS with those of tubes . That is to say that they will not be rolled off at the extremes . My Primaluna Prologue 2 is one example . But , as Aball eluded to above , you may need more power than the 40 w. that they produce . Higher powered tube amps can get expensive .

Good luck .
