Power Amp for Focal Scala Utopia Evo (Pass, Luxman, Moon, Mc, or Audia Flight?)Hi everyone

I have these speakers and power them with 2 vertically bi-amped BHK 250 stereo amps.  These amps have a tube input stage which helps bring a bit of warmth and it allows me to tailor the sound, just for the tweeter and mid or separately the woofer.  I did some tube rolling with a set of NOS tubes and it really opened up the sound stage.  As you know the Be tweeters require the right electronics.  I have listened to your speakers with a Luxman and would not recommend it.  From your list, I would lean towards the Pass amps.  I would not go less than 200 watts.  True these are not hard to drive, but you need power (current and voltage) to drive the large woofer.  I tried these speakers with a 100 watt benchmark amp and there is an improvement with more wattage - went from hearing the bass to feeling the bass.   If I was going to upgrade someday, which is not on my radar for an amp, it would likely be Pass monoblocks or two stereo Pass amps biamped.  I am not a MC expert, but when I listened to their amps they were a bit soft.  Nice relaxed pleasant sound, but with a speaker as accurate and detailed as your Focals, seems to me a bit of a mismatch.  I can't comment on the other two brands having not heard them personally.  As others mentioned, what are you trying to improve and how to your prefer you music?  Crisp, warm, bright, mellow, bassy, not bassy.  Everything will drive the speakers so pick the amp that tailors the sound the your preferred sound profile.  

@darkknight8586 get the pair of MC611s. Perfect costing

Dear @darkknight8586  There are several fans for the Macak electronics since several years.

Problem is that are coupled by Transformers and the signal must pass trhough thrrible transformers degrading the recording signal no matter what.

I would be hesitant to pair Focals with Simaudio Moon. Unless you are into presentation that’s on a cooler and more analytical side where you can witness autopsy done on every recording you play.
Could be great but will most likely be fatiguing.
 

I’d opt for a Pass X350.8. You get Class A power for the first few important watts, plus the huge headroom and current for excellent bass control. Remember , bass is what you need as a counterbalance the hot beryllium tweeter and keeping the overall sound balanced. You can pair the X350.8 with a nice tube preamp if you desire.
