I finally finished my SEX 2.1, it sounds fantastic, nice detail and did not explode, or catch fire when I plugged it in after the checks. It will be shown at the Northern California DIY show in May in Davis.
I am using speakers, at the moment it is hooked up to a pair of EPI 100 speakers. Next set to be hooked up are a pair of Fostex FE103EN bass reflex speakers. When I received the kit I actually considered selling my 2.0 for a split second. Then reality hit, it's still is a great sounding amp that I have always enjoyed demonstrating in audio shows and meets and is one of my favorite amps.
