Well, I took the plunge and bought an eden wt405 on ebay. The auction had 3hrs left and I had to leave for work 30mins after I came across the auction so it was a bit of a quick decision. I made the decision based on the following: The eden 550 was on my short list, along with the carvin b800/500 and GBE 400/500/600. I had also been thinking about the 405 since its a little lighter (15lbs) and it puts out 620w at 2ohms which is more than enough for me. Also, I have read on TB that eden watts are rated conservatively so the 405 at 4ohms should do me fine with my 1210 (if i keep the 1210). I know what edens sound like and I like the tone. I think it will sound very good with the wizzy stack. I asked some questions on the eden forum about running an eden at 2ohms. About 10 responses said I should have no problems with many of those saying they always run their amps at 2ohms with no concerns. Eden amps have a good reputation and if it isnt for me, I dont think I'd have too much trouble selling it. I think I paid either market value or perhaps a little above at $615USD, but i had to make a quick decision and thought I'll just make the minimum bid (the only bid) and if I win it, it was fate. I really dont believe that, but anyway... The amp was a demo unit at a music store in kentucky. i asked the seller some questions about wear and tear, but if it was new and then demoed in store, I am hoping it wont have any issues. I have always thought of owning an Eden at some point in my life. This amp with two wizzys will be quite a nice rig I believe.
