Focal Grande Utopia EM Evo*

[Masterlu]

I also want amps that have 1200 watts @ 8 ohms per channel; possibly two per side.

This would be an incredible system!!

I'm using Boulder 2150s monos (1000w@8Ω) with my focal Stella EVOs, I could see how more power would be of benefit with the big Grand Utopias - they go really low.

Exactly, I usually double the maximum recommended power for extreme headroom.

It seems that Boulder 2150s mono is 1000 watts peak power from their product spec page...a bit misleading, would have been far better the actual rms rating..

Parasounds JC1+ 1300 watts rms at 2 0hms and stable with impedance dips below
1 ohm

Bi amping with JC1+ should be breathtaking!!

Happy listening

Rats!
Foiled again.
Plans are to be up by your area before Father’s day.
Hopefully I wont get sick this time.

Please! The JC1+ is a fine amp, don't get me wrong -- but nowhere in the same league as the boulder 2150.

Have a look JA's measurements

JC1+ delivers:
450W into 8 ohms
850W into 4 ohms
1200W into 2 ohms
https://www.stereophile.com/content/...measurements-0

2150 delivers:
960W into 8 ohms
1450 into 4 ohms
House circuit breaker tripped before he could measure the rated 4000W into 2 ohms
https://www.stereophile.com/content/...r-measurements

To get the full power out of the boulder, you need 22amps at 220v input or 45amps at 110v as it consumes 5000w from the wall.

And the 2150 is pure class A. The JC1+ noise measured at 1kHz at 53W into 8 ohms, 0.0049% THD+N. The 2150, pushed way harder, measured an order of magnitude less noise 1kHz at 400W into 4 ohms, 0.00036% THD+N

I'm not really a measurement guy, but sometimes they are useful for context.

Ivan,

I've been a long time focal owner and fan -- Alto be, Scala, Scala v2, Scala Evo, Maestro Evo and now Stella Evo.

I was having deja-vu hearing you talk about focal. I went back and found this 'last hurrah' thread in 2019: https://www.audioaficionado.org/showthread.php?t=46148

And even as far back as 2014 you were considering their predecessor: https://www.audioaficionado.org/show...ghlight=Utopia

It seems they have been calling your name for a while

What a great read from a few years ago. You’re right, they are still on my mind.

I should've known ....but could not fathom why Boulder would use an obsolete
power descriptor peak power...

In a review by audioexpress the reviewer could not get max power output
from a Parasound JC5 because the wall voltage sagged not allowing the
JC5 to perform at it's fullest and recommended 25 amp dedicates lines

Thanks for the heads up..!!

Happy listening
