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

Rather than buying more power than you need, given the comment about vocals sounding metallic, perhaps you ought to consider having two systems,

1. tubes (both preamp and amp)

2. solid state

I used twist/tightening WBT banana plugs with a junction I could easily reach, had 3 going, tube mono-blocks; tube receiver; solid state. Different colored tape on the 3 sets of speaker wires

tightening banana plugs

Surprise, the tube mono blocks had enough bass, everyone always chose them. Source, I have several in CD; Vinyl; Reel to Reel tape. Surprise, everyone always chose the Tape, even though it has more noise if just comparing specs.

btw, I expected to see Accuphase on your list.

In my opinion, call the manufacturer and see what they use to demo their speakers and also their dealers.  The demands of an individual speaker needs to match up with the amplifier.  Hopefully they will provide you with various amplifiers they have tried and how they sounded.

Happy Listening.

The Boulder 1162 would be worth an audition. Good luck !

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.
