The Cayin has only been run in PP (35W) so far. My mains are Maggies, so the 4W SE mode would not bring anything to the "dance." I'm hopeing the Pi's I enventually order will work well with the Cayin and SEX kit. Damn, I'm going to need two pairs of speakers. The list price of the TA-30 on the previously mentioned site is no where near what I paid. I got the bare-ones (sans Auricaps) model w/ sub out for around $550.
