Lowrider I have owned a CJ premier 14 for many years, it is currently playing backup to my Dehavilland ultra verve. The UV is slightly more revealing than the 14, just how much depends on the 6SN7 signal tube used. The CJ with Mullard tubes has a more refined sound than the UV and not quite as "open" sounding through the upper regions. It also gives a row M feel and the UV makes you feels like you are closer to the stage. The midrange on both are good, the CJ as I mentioned shows slightly more refinement and is more round and dense in this region. Dense in a good way. I do not like the GE 6gk7's that CJ supplies, much different sound than the Mullards.
I like both preamps and use the both. The CJ has always matched nicely with my Thiels which need a little help in the mid region. Good luck with your choice.
