Just an update on my Rachael amp. Grooving to some Earth Wind and Fire this morning and am just gobsmacked at the sound. This amp gets the groove right! She has opened up over time and I am getting pretty good headroom with the Zu Omen Definitions. Speakers just disappear, soundstage is huge.
The next step is putting the vinyl setup back together.  A Well Tempered Versalex and ZP3 might be in my future to go along with my Koetsu Sky Blue. Gonna be a great summer!

I have Zu Union Cubes and this amp works very well for me. I am interested in the CKCS monoblocks so I better hurry and get my new DAC set up and turn the music back on!
