How big is your room? I have Scala + 2 REL S510 subs in a 20x20x9 cu ft family room (but opens in the back to foyer / living room that is another 20 ft long) & the Scala is more than sufficient.
Frankly (& this is IMHO only): most of the Utopia quality is due to the construction style (different cabinets for different drivers) and materials used.
Scala V1 vs V2 vs EVO - make a small difference (regardless of what the marketing material or its audiophile followers say) - small tweaks but the rebranding was essential for bumping up the speaker price from around $26k to around $55k. As, when they came out with this speaker, they realized that they underpriced it relative to the competition. Blasphemous, yes, but true.
I went to buy the Scala Evo. But, the dealer also had a pair of Scala V1 for sale (via trade-in). He was nice enough to have the V1 vs EVO side by side for me to audition so I could check out the difference.
Also: was reading a few of your past posts and was surprised that your Maestro (which, I’ve heard, needs ample current) was run by Luxman amps (the M900U?).
For my Scala, I found great benefit when I moved to the powerful Hegel H30 (320k microfarad capacitance!).
