This is my experience: I began with Hubble Cryo version (like Porter outlets). The difference compared to ordinary Hubble outlet was huge. I moved to SR tesla Red and it was even better. Then I replaced them with Furutech GTX-G on amp side (Solid state) and GTX-R on sources/preamp. I found more improvement on both frequency extremes, much better transition on notes, better sound stage and much better articulation on vocals and notes. Most people suggests GTX-Rhodium for Tube based systems like yours which is well justified as reasoning, also based on my own experience. There are tones of comments about Oyaide vs. Furutech. I would recommend this article too:

BTW, I've never seen any review about SR Black UEF! However, I would guess it has same sound signature of SR outlets which is very open on High frequencies.
hope that would help...
Cheers.
