That may be a 92.5db/w/m speaker but it's a crossover intensive, multi-driver speaker. Few modest-power tube amps will resolve that Focal's problems (or challenges) and you don't want the mega-massed-tetrodes/pentodes 200w+ tubes monsters. What can you actually spend on amplification? I'm a tube loyalist but sometimes you have to accept a solid state alternative. IF you can afford to, the SST Ampzilla 2000 Second Edition (temporarily $5200/pair on promotion) would give you tube warmth and scintillating solid state resolution + faultless bass control. Magnificent on that speaker. Also the SPL S800 stereo power amp. And for much less, the m2tech Crosby, either as a 60/60w stereo power amp or as 180w monoblocks (8 ohms), would obliterate most tube amps on that speaker. The Crosby is $1300 for stereo, $2600 for a pair of energetic, high-grip monoblocks. Tube smoothness with transistor assertiveness and control in an 8 lbs. per monoblock compact package. What are you game for?
