Never heard the C+ but am still enamored with my 10 year old Select. It recently put my girlfriend in a trance. Also, when she saw the amp she said, "it looks like some sort of machine". She never heard tube audio before - nor ever heard of tubes - but when I played some Loreena McKennit, James Taylor, and meditation music through the system, she literally stood there dumbfounded and said the proverbial "it's like they are in the room". After she sat down, I played Marina Raye's
Blissful Journey and my girlfriend (who is Buddhist) crossed her legs in the chair and began to meditate. Talk about "Zen"!

I've had an urge to add a bit more power to my system (either the Mono's or a Torii III) but am not sure at the moment. Not sure how they would mate with my 2 ohm
Parker 95's. I was thinking of adding an
HSU ULS-15 sub to add more base extension then decide after that what to do.
I am open to suggestions.... I have also kept my eyes open for the older Zen Monoblocks but they don't seem to come up often for sale as in the past.
A testament to Steve and his work. Even makes non-audiophiles standup and listen. They know something special is going on....
