AES/Cary DJH Preamp tube change

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.
