Your Pass amps have plenty of power and should be a wonderful match for your speakers. I have always liked the liquid sound of Pass amps (I used to own the XA160). Before buying anything make sure you listen and live with the Pass gear for a while them decide what you like or don't like. I also highly advise sorting out your room treatments before swapping equipment. Until you can accurately hear what your system is doing it will be hard to pinpoint what you need. As for the spikes, I advise to either use pennies under them or buy some nice disks from Starsound, I use these.

Focal Dealers told me that the Maestro is the most demanding speakers of Focal , even more then Stella and Grande
because of the magnetically damped woofers.

they told me also My Pass X350.5 not even close to getting the best from the Maestro.

one dealer recommend the Aesthetix Atlas Mono Amps and TARA 0.8 EX interconnect and speakers cables.

what do you think?

I can only dream of owning speakers such as those Focals. But to answer your question, the Pass amp should easily drive them. Focal Maestro Utopia has high sensitivity and your X350.5 puts out 700 wpc into 4 ohms. The Focals are rated at 4 ohms, but can drop as low as 2 ohms and IMO the high current of the Pass amp would not have a problem.

I see that owners report a long burn-in period for the Focals, so give them some break-in time before you judge them.
And unless you make some changes to your room acoustics, you will never get the most out of your system. There were many suggestions in your other thread.

Reading the specs on your speakers the X350.5 is more than enough power. They are 93db with a 4ohm nominal impedance and dropping to a minimum of 3ohm; a fairly easy load for the 350.5 in my opinion.
