Here are my results.
I'm happy to say, there is a noticeable difference having added the UPA-2. At first, I could not tell. After 5-10 minutes I noticed the difference. I put in Metallica, the black cd, and played some songs. That's when I heard the detail, fullness, and the dynamic range of my speakers. I was waiting for my Focals to sound as they do now. I remember thinking, they sound and feel underpowered. No longer. I'm definitely satisfied with my purchase. I'm glad it worked out, as now I'll be set for hopefully quite some time. I felt like if I got the XPA-3, it might almost warrant an upgrade of my mains. Having just got these Focal mains, I'm now satisfied. I'm also getting some new speaker cables from Blue Jeans Cable for my front mains and center. Sweet.
There's my brief review. Overall, I'm happy with the UPA-2. It has definitely improved my front mains, at least to my ears. My roommate also said he thinks they sound better too, more dynamic was his words.
