I just finished an extended listening session, and a few things stood out with the NU 7193s.
The highs are extraordinarily detailed and sparklingly clear. They might be fatiguing if it wasn't for the total lack of glare - these tubes are clean, clean, clean. This probably has to do with the anode and grid connections being through the top caps, a design feature which was adopted specifically to improve high frequency performance in radio frequency applications, according to several on-line sources I have found.
The mids are very natural and warm, but not as warm as those from the RCA Grey Glass 6SN7s, which some might consider overdone. The harmonies on the Beatles "Love" CD were thrilling.
The bass is about the same as I had with the 6SN7s, maybe a bit tighter. I'm looking forward to receiving the Ken-Rad 7193s (which should have been here by now...) as Ken-Rads are well-known for their prodigious bass. Stay tuned.
