Conrad Johnson Premier 16 LS and NOS Tubes - Help

I owned a CJ17LS and used a AudioPrism power cord and NOS Amperex tubes both of which made a huge improvement. I then upgraded to a CJ16 Series 2. The NOS tubes and power cord made very little improvement to the sound. My local CJ dealer heard the same thing as we did this one Sunday at his store. My recommendation would be to send your 16LS to CJ for the upgrade rather than spend $'s on NOS tubes and a good power cord.

Kevin Deal at Upscale Audio is a great source for tubes; he sold me some tubes for my Audible Illusions L1 that has it sounding great!

I have the 16 Series-2 which came with the stock Sovetek tubes. When I changed over to Siemens, the change was not subtle. Much smoother highs, more pronounced bass but not mushier. I guess more organic sounding overall.
