I am just the person used these 2 speakers.
My description is that Mezzo Utopia is more like a
full-range football star, brilliant and rich, mid is
best above all. But a bit too "full" in Mid sometimes.
Parsifal ( encore - I use, not Ovation ) is more like
a full-course scholar, detailed in all aspect, low range
may be a little muddy if used backward-facing, and not
more than 60 inches ( tweeter front measured to back wall )
If you like sweet, detailed, fine & rich, more relaxing
Parsifal will be your choice. I have not regreted having sold
the JM and still keeping the P/E for more than 3 years now.
( But the factory provided Jumper from Verity is actually not matching the speakers , I upgraded the jumpers with
Siltech emperor G6 Satt Version and enjoyed the old
"Encore" even more than the Ovation's I listened at
showroom and one of my friend's house ( even he claimed
his Ovation with factory jumpers are not sounding as good
as my " encore " with siltech Emperor's.
