I just got a mini stack and have decided to try a different amp. I've read all the threads I could find and it sounds like the ABM 500 and Thunderfunk amps are good choices, but they're hard to find used. I don't recall any mention of using an Eden WT-550 with them though. Has anyone used an Eden WT-550 with a mini stack? If so, what did you think of the combination? Did it have enough power?
