Hi Dennis - if your KenRads say VT-231 they are in the middle of the 3 sonic spectrums I've mentioned. In my system I find these to work the best - yes, their sound could be interpreted as "veiled" when compared to other 6SN7's but they deliver a weight and body that no other tube I've found can match. The rounds are much more open, a bit sweeter and dynamic.
In my system, I'd say my room is slightly "live" - so that adds a natural "air" to some extent. The KenRads tend to roll the highs slightly, push the midrange and give the sound a more natural overall timbre. Voices are much less metallic than with other tubes (Sylvania 6SN7W metal base).
I've found that most every tube has trade-offs. You just need to determine where in your system you can compensate for those.
There is never a sure fire tube implementation that works perfect in every system & for everyones taste (as I am finding out with my Aesthetix IO). The best solution is usually to try as many as you can.
