Conrad Johnson owners -

I currently own the CJ CT6 preamp and I am looking to upgrade to either the CT5 or the LS16II. Is there anyone out there that has heard both of these in their system or can tell me if there is a sonic difference between the two.
Is there one that you think is better and why?

I have owned the CT5 and CJ LP70S combo for 12 months or so. I think Tomcy6 is spot on.
I was wondering what CONRAD Johnson Ass amps are known for, there quality, and what there owners love about the,
The CTs are of the same vintage, 2005, where the LS16 II is earlier, 1998. Have you considered the ET5? It is better than the CTs and is comparable to the 16, but maybe a hair cleaner and more dimensional.
