Contemplating the EDEN 1205 as my next amp, but discovered they have been discontinued. When did Eden drop them from the line-up? I know they changed ownership a few times in the past ten years... what's up with that? Read a few 1205 reviews concerning poor pre-amp gain and AC power supply noise, but there are factory mods to address these concerns. How is Eden with customer service on these and/or other problems (i.e. warranty service)? Anybody experience other issues with the 1250?
