Well, here's one I didn't expect. I've got a Thunderfunk 550 that I've really liked and have used with an Epi UL-310 and a UL-112 and both sounded great. Through a series of G.A.S. induced bad moves I sold both cabs and regretted it, so I thought that since I've been pleased with Epifani stuff so far, I'd try a pair of PS-112's. I got the PS-112's recently and was immediately underwhelmed. I missed the clarity I'd had with the other cabs and the low end seemed to be more boomy than the fullness that had been described. Just for kicks I borrowed a friend's Clarus series II. I brought it home and plugged in and was immediately and unexpectedly impressed. I had the clarity I'd been missing, the low end was full but more controlled and it was LOUD! The Clarus was only pushing 200 watts at 4 ohms, but was tighter, smoother and warmer sounding at a high in-the-house volume. I think the Thunderfunk would win out in a loud band situation and certainly has a more flexible preamp, but for what I'm doing I'm thinking an AI amp may be the better choice. It may be time to change to a Series III Clarus or maybe even a Focus. I may see if I can find some kind of Thunderfunk/Acoustic Image trade +/- cash deal.
