Anybody Use an Audio Research Ref 6E?

I am focused on buying a Ref 6E and curious to learn experience of others.

i see used 6 models for about 11k and these seem tempting as the 6E jumped up quite abit.  17k is a high price given pricing on a used 6 but I do like new.

the ref 6 is a good way to get into the game. You can upgrade the ref 6 to a ref 6se for 3k later when you have more cash
Why do you keep posting questions about preamps in the digital section? 
You r right. I forgot why I was.
