Velo-
I have only used the stock tubes to this point, so I can't comment on your kt-88's. Did you try the el-34? I am unsure how the kt-88 would effect the character.
I am using an unported sub to uphold the bass foundation of some small Dynaudio speakers. I notice the Cayin to have a different bass line than my SS. I live for the midrange, soundstage and overall presence I find the ta-30 produces. I am pretty sure it won't have the bass slam of your CJ which I think has something over 100 watts/channel.
I typically listen to late night vocal, acoustic music and classical, I like bass, but too boomy wakes wifepoo up and causes problems. I was playing Aretha Franklin gospel (Amazing Grace album from '72) last night, it had a huge bassline and I had to turn the sub off. I ended up plugging the rear bass ports to keep the sound from shaking her awake upstairs. I really like how this unit is working out, the complete sound is the best I have heard in my 'not the best acoustically' listening room. Of course, each room/ amp /speaker combo will react differently.
One thing I noticed about the ta was it showed limitation in the height of my room. It is a low ceiling (basement 7.5 ft) and I find the sound seems like it wants more room yet to expand. This I had never noticed before. The width of the room is 20 ft and it is 15 ft deep. Ideally I would reverse this with the spkrs at the far end to make the proper stage, but other reasons prevail. In a 12 by 12 room it might seem stifling especially since bass might take 20 ft to develop properly. Have you tried the ta in a larger room?
