One thing you may also want to try is HomeGrown Audio's version of KCAG. It is only $70 for 1 meter(terminated). It is the same as KCAG, only using solid core silver wire(as opposed to stranded). I find it better sounding than Kimber. Less edgy, metallic, shrill. Yet still accurate, detailed, and extended. Jadis doesn't recommend KT88, as they feel they are unreliable. I have investigated this, and found there was a period when Tesla(also known as Teslovak, and now JJ) KT88 were very unreliable. Recent production has been fine. I would first recommend getting the HomeGrown Audio cable, give it a 200 hour break-in(it may sound terrible even at 50 or sometimes 100 hours - there is an easy way to break in cable without turning on your amp, which I learned here on Audiogon). If you still find yourself craving the warmth, then try a set of KT88s. Also, will your CJ Premier 12 accept EL34/E34L/6CA7 tubes? I would e-mail Conrad Johnson with this and other questions. If you REALLY desire your CJ to sound sweet, warm, and romantic, the EL34 types are the way to go - classic tube. You would also be paying 50%(or less) for this type of tube(good now, and great in the future). What kind of speakers are you driving? Assuming you have an abundance of power now, you don't have to worry about what you'll lose when you switch. And they work beautifully with silver cables. Good Luck!
