I have had Aleph 0 monoblocks for some time running the midrange on my Linkwitz Orion's. I am using the J2 to drive the tweeters. So I recently bought a few monitors, the Focal 1008's and Usher BE-718's, and figured the Aleph 0's would be a good match with the Aleph P preamp I also have. So the Ushers sounded a bit anemic with the Aleph 0 so for the fun of it, I tried the J2. For some reason, the J2 appears to drive the Ushers better and with more authority than the 0, which is far more powerful. Other than the J2 being 20 years newer, what could account for this discrepancy/conundrum? I was told the 0 measured to spec when I purchased them last year.
