Kimber vs Jensen coupling caps in Cary amps


Anyone compared 0.22 mf Kimber coupling caps in Cary amps? I have purchased Jensen copperfoil/oil caps, opened my Cary SLI-50 integrated and saw yellow Kimber metallized polypropylene capacitors. Are they any good and will the Jensens be an upgrade?

Coupling caps are not a must in tube amps. All of my amp stages are transformer coupled and the only caps are oil/film caps in the power supplies.
Transl, is anything touching the v-cap capacitor such as self stick tape or sticky putty. I have found that teflon capacitors (perhaps others) can take on the dielectric signature of something touching the outer case.
Hi
I installed .22uf Rel Teflon's in my Cary Sli 80, replacing the Audio 1's. Thay take a long time to break in, but the difference was astounding! Everything opened up. I lifted a heavy veil from to to bottom.
I replaced the Kimbers with Jensen, they were better, more soft sounding though.. however Mundorf Silver/oils are superior to the Jensens in all applications I have used either. Only reason I even started in with the jensens is they were available to me before I ever knew about the mundorfs.
