AES/Cary DJH Preamp tube change

Hi,
I purchased a AES/Cary DJH preamp along with there six-pacs about a month ago.(very impressive set) I also felt I needed to change out the stock 6sn7 tubes in the pre/amp, I did buy the Electro Harmonix with the gold pins, and YES there was a definite improvement in sound, The sound become smoother more defined, detailed and in a way cleaner, not that the stock unit was bad at all.
I think it was the best $ 53 I spent in a long time, and I want to replace the six-pac with them when I find them .

Szunker, where did you get the EH gold pin 6SN7 from?

Hi,
I purchesed the 6SN7 EH with the gold pins from "thetubestore.com also I have seen them listed at "tubedepot.com".
p/s when you get them tell us what you think.

I use the AES?AE-1p
I found that the best tubes for "ME" were NOS. RCA w/red lettering

I upgraded my 6sn7 tubes with EH tubes because the cost is reasonable. They tightened the bass and extended the highs. My system has better drive and control and is more refined than with the stock tubes. There may be better tubes but at $12 each for the standard version you can't go wrong with this experimentation.
