Received the tubes yesterday from Cyroset. These are beautiful tubes. Smaller then El34's but heavier glass and really well made. You can see the superior quality over JJ's. There slim shape fits the Torii tube sockets really nice as the base fits between the screws that hold in the socket, so the tube can't rock back and forth. Also, the tube fits more snug which is nice.
Immediately with no burn you can hear that the sound signature is quite different. Bigger sound, more weight and authority and yet still somehow even more midrange emphasis on vocals. I first did a comparison with some Bob Dylan mono recordings with JJ 6AC7's on one side and the KT77's on the other. Switching and back forth showed the KT's made Dylan's voice come much more alive and to the forefront. A more euphoric, richer presentation. The bass on these is extraordinary. I already have good bass, but no with change to my bass controls, it is causing vibrations in my room. I have a little wooden chess set on top of one speaker, and the bass knocks the pieces off!
After some burn in and critical listening I report back but so far they seem very promising. I will need to see if I lose any transparency. I am using the 1970's 6N1P's from Cyroset as input tubes. I placed in the Gold Lion 6922's for a bit. But shuddered and took them out right away. Really harsh. I will try again later and see if lots of burn in tames them down, but like Lon, it seems like 6922's just aren't for me.
