Focal Maestro Utopia , need advice for AMP/PRE

Pelo911, X350.5 should be more than enough. I use Burmester 032 (I haven't updated my page yet). Though 032 is being strained at times (it is only 170W into 4ohms). If I were you, I would first break in the speakers with your current amp and consider upgrade later.

One possible candidate I saw listed.
Right voltage, right price if you are from Europe.
300w into 8ohm should be plenty good.

Simplification of system i.e..less cabling, less rack space etc could also be a welcome thing in your situation.

"few focal dealers that know the Maestro
told me that the Pass Labs not the best choice for the Maestro."

Who cares what the dealers say? They aren't the one who are going to listen to your system in your home. YOU are.

So what do YOU think? Is there anything you dislike about the sound of the new speakers with your current Pass amp and pre-amp? Is there anything you think should sound better?

Until you can answer those questions - and you won't be able to until you allow time for the speakers to break in - you are just setting yourself up to spend money for no good reason.

i have Focal Maestro with Mc Intosh C50 and mono 601.
Cables all Mit Matrix.
The sound is fantastic with very good bass.
My speakers were Wilson 5, Canton Reference1, Focal La Scala,
Magico V3 and Magico Q5.
I 'm happy with my current system,

Final pudding is always in the listening.. But I do believe by gathering opinions from
fellow owners, experienced Agoners, knowledgable Dealers, as well magazine reviews,
will aid form a good baseline to streamline one's choices.

It is not logistically practical to bring every conceivable candidates for home audition -
Do it (by all means) when down to your final two or three. Likewise, in the instance
products we desire not readily stocked locally (pre-order only), those collective insights
could also be particularly useful towards our decision making.

But yes, best to start auditioning only after things have properly settled and bedded-in
in order to avoid unnecessary/costly mistake on your part.
