Very interested in A-B comparisons with these amps too. Both are on my shortlist, but I live in Australia, so very hard to audition. At the moment I'm going with the highly praised combo of a Peachtree iDecco with Gallo Strada and T3 sub. Audience AU24 cables, and Synergistic Research Precision AC Basik, Chang Lightspeed X Series H1 conditioner. Looking for more power, less sibilance, more warmth. I love the resolution and speed of the Gallo's but miss some richness.
