Pope Holland Tubes for Cary SLP98P


I have read some good feedback on the Pope tubes for the Cary preamps, does anyone have experience with them and the Cary? Is it worth $600 to upgrade, is there that much improvement?

thanks for the suggestions, much appreciated.

Mechans,

I had never heard of Pope tubes prior to about a week ago when I searched tube rolling on the Cary SLP98 so you must be thinking of someone else. I like my preamp a lot, I am just wondering if it's worth $600 or should I move up to the SLP 05 and get a seperate phono stage?

I may try rolling the tubes first.
I have an SLP-05 and the Popes were the best for ME out of the 10 different tubes that I tried. I have the set that's in the pre and some spares...
I have the Pope 6SN7'S in my My Cary SLi80 and they are best I ever heard and I have tried about all them.
