Focal Maestro Utopia , need advice for AMP/PRE

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.

they wrote that this speaker need powerfull AMP

"However, it demands to be used with amplifiers unfazed by its wicked load impedance in the upper bass."

...From the review: your Pass qualifies.
Don't be influenced by your dealer that you need a new amp.

Pelo..., congratulations on your new Focals. Although I don't know much about the Focal line, you may want to reach out to Albert Porter. His system is always attracting comments in Virtual Systems. Albert's rig includes Focal Maestro Utopias.

Btw, the Focal 1038 - Be II are on my short list of speakers that I'm eyeing -- or better, "earing"??. Can you share any thoughts about the 1038s? Are they high current power hogs? My amp is an ARC Ref 150 tube amp which is rated at 150 wpc and has relatively low output impedance. Any thoughts about compatibility?
