Phd: Yes, I did indeed get off topic here. Sorry about that.
Bostonjim46: Congrats on the JL1's. I run with the JL-3's and discovered a greater degree of fullness and textures in the mids when I changed out the stock small-signal tubes. The Mullard 6922 and 12ax7 made a huge improvement not only in the portrayal of space but also dynamics. The latter is a Mullard strength. The Telefunken 12au7 over the stock 12au7 was a very slight improvement in the clarity of the mids. I have since discovered the Telefunken 6DJ8 which is absolutely magical every place I have tried it. But I have not yet had the chance to try this with the JL-3's. So try to locate some of these and discover even more with the CAT amps.
Andrewdoan: I have been to many rock and jazz concerts and so often the bass is boomy, the amplification used by the facility is terrible, and its downright impossible to hear clearly what the singer is singing and/or saying. If I want great sound quality, I am pretty much limited to the smaller venues or the great orchestra halls. The places we hear our favorite bands is not even remotely close sonically to where the studio recording was made that we listen to in our homes.
I go to a concert simply for the opportunity to see my favorite musicians. It's an issue of having fun; the ultimate sound quality is not a factor here.
As for the issue of one's tube gear causing major colorations, the recording engineers had far more to do with altering the sound than any tube-based home system playing that altered recording.
