Teflon Cap upgrade or new set of NOS tubes for conrad johnson PV12A Preamp?


Unit sounds good now but was wondering -- of these two choices what will sound better?? For CJ PV12A  to have CJ install new Teflon CAPS or replace all stock tubes with NOS high end?

@erik_squires ,

I believe the OP wants Conrad-Johnson to do it.  The Teflon caps are made by CJ or are branded as such and everyone who has bought the unit with the better caps says it is worthwhile.  They also take a few hundred hours to break in.
I recently had new Teflon caps installed in my CJ PV 11.  It certainly was worth it.
 It’s like acquiring a new premium preamp. If yours has a phono section, it’s especially worth it. Probably superior to any stand alone phono preamp out there,
the CJ phono section is very special.
Btw, two Telefunken NOS 12 AU7s are not too expensive and sound wonderful in the line stage.
I have a humble c-j Classic 2SE with the teflon caps....   it is such a great sounding pre.  It was a $500 premium over the base Classic but well worth it.  I auditioned it against a base  ET3 in what had to be a $50k system and liked the Classic 2SE better. 

If you really like it, why not do the caps ?   It's a great preamp that is worth the upgrade.  Outfit it with the best new production tubes , or NOS if you have a reliable source like Brent Jessee or Jim McShane and have the $$$ .    The teflon upgrade isn't cheap , but it's a fraction of a new preamp.
