If you do try out the EH, please let me know your thoughts regardless of how subjective they may be. It's 2x the price of the Tung-Sol and I spent most of my $ on NOS. Most of those NOS cost more than the Tung-Sol reissue, so I was very surprised by the high SQ. I held off on the EH due to it being close in price to the GE's (disappointment) ... but I really would like to know how they work out for you.
I tried the EH tube, but it's not for me. It has good bass extension and sound stage, but the treble is too bright (and slightly strident) for me. I've probably had the tube running for 30-40 hours before giving it a good listen today. Maybe it needs more burn-in?
Anyway, back to the stock tube for a while - and I really like how the Saga sounds with the stock tube! The Tung-Sol is next.
