CAD SLI-80 Signature: Re-tubing

Decided to re-tube my demo SLI-80, as it makes me a bit nervous to not have an accurate idea as to how many hours are on the power tubes.

I definitely won't miss the cheap Sovtek 6550's that came with the amp. I very much prefer the sound of the Svetlana/Winged C 6550 variant. I am looking for feedback from SLI-80 owners that may have tried using EL34's or KT88's, and which tube they prefer. How does the sound and/or power output differ from one tube to the next?

Thanks,
Chris

I use Sylvania 5U4G rectifiers (and RCA 5U4G which are a bit darker), TungSol three-hole grey plates 6550, Sylvania VT-231 (and sometimes KenRads JAN CKR 6SN7GT which are very colored but good and GE 6SNTGTA and GTB) and Siemens 6922/Amperex 6922 orange globe).

I also tried the Mullard EL34 xf2 and xf3 but was not very much satisfied but I found that the RFT EL34 are rather good with this amp. YMMV of course.
