Conrad Johnson CT6 Teflon upgrade, anyone done/heard it?

Hi Jafant, yes we do seem to be a rare breed! There must be more of us CT6 owners out there?!!
Its a nice pre, lovely harmonics, voices are sublime, good detail but room for improvement of course, it does most things very well but I'm sure it would really elevate with the C1 Teflon upgrade, just want it from the horses mouth.
Im in Europe so US equipment is priced at a premium, got a good price on the CT6 so with the upgrade would actually fall into the same price range as a used CT5 or 16LS which are very RARE to find in EU, just wondering how it measures up against them? 

Its fairly new to my system which consists of a heavy modified Rega RP6 with audiomods tone arm, Ortofon Rohmann, Jasmine LP2.5, Cary audio DAC200ts w NOS telefunkens, CJ CT6 w NOS Amperex Herleen, Pass Labs x150.5, Sonus Faber Cremona, Sonore power filter/block, Yter speaker cables, homemade interconnects - Mundorf silver gold cables terminated with KLEI absolutes and all Harmonic Tech pro ac11 power cables. Sounds mega but of course half the fun of high end audio is the chase. Now i have a ball and chain i must find my chases elsewhere and audio was the natural progression : )  

Have not heard it with the upgrade.  I did own the preamp at one time though.  Sold it and found a Pr16 that I enjoyed quite a bit more for a number of years.

Also thought about doing the upgrade to my CT 6 before selling it.  At the time I was given the same advise that I gave you.  But I preferred the Pr16 to the CT5.   Won't name names regarding the person who gave me the advise but the company that he worked for had the initials CJ.

Another way to look at it would be to comparre the 17 S2 with Teflon to the 16 without and the CT6 with Teflon to the CT5.   In both cases I think the 16 or CT 5 would be the better option.  

Excellent system-  shertzy

How are you likng the Conrad Johnson/Pass Labs combo?
More audiophiles are turning to CJ and Pass Labs in concert w/ one another.

Do you have a source for the modifications in Europe?

Happy Listening!

Thanks for the info guys. I am thinking of doing this upgrade and others myself as a bit of a project, Jeff from CJ has gone silent on my emails about upgrade inquires so it seems this is the only way forward, it will be massively cheaper and i can put the exact components in to suite my ears needs - detail, musicality and warmth. Watch this space!
