Replace CJ with new equipment

The E-250 is an excellent phono. In the same price range as the Parasound JC3+. But I think sounds better. Plus it has a mono switch and a cart demagnetizer. The phono in my preamp is all tube w/four step up transformers. Two for MC High and 2 for MC Low. The E-250 also has a step up transformer built in too.

The quicksilver gear is nice stuff. But before you toss you CJ I would agree with
 erik_squires. lots of options for the PV12 and premier amp.

1. move to a copper foil coupling cap from either Jupiter or Jensen.
2. drop the plate load resistors to allow some current to flow to those tubes. In the stock state, the tubes are starved for current. Sound will open up and sound more relaxed.

3. for the premier amp, do same coupling caps.

Those are both great pieces, I would freshen them up...  That amp has plenty of power for those K horns,  and they will cost $$$ to better.   

Quicksilver Amps are great too, I have Mid Monos and love them.  They just came out with 60 watt monos that are $3k that I bet will be a huge value like their other stuff. 

I would be inclined to mod/ refresh the CJ gear IF you want refirnement
go shopping IF you want a flavor change

I would like to add that CJ and Klipsch make a great combination.   I have some La Scalas and always wanted a PV 10 to match up with a small McIntosh I own.
