Electro Harmonix 6922 pre-amp tubes

Thanks Newbee, From your description, think I will stick with the sovteks in my BAT phonostage.

I currently use the std EH 6922's in My Audio Research CA50 where they replaced the original Soveteks. To my ear they are slightly warmer than the Soveteks and still have the rugged reliability required in the ARC & Audible Illusions products. The JJ's sound wonderful but so far have cost me in the neighborhood of $400.00 in repairs after catastrophically failing in both the CA50 and my SP9MKIII. I did try the EH6922's in My SP9 as well but liked the warmer sound of some NOS Valvo 7DJ8's that I had in my stash as the SP9 can be rather sterile sounding with the wrong tubes. Good Luck.

Regards, Jerry

Tom, FWIW I just finished playing with the SP10 (aqain) today. I tried mixing some Sovteks and EH's in my SP10's line and phono stages. You can try putting some EH's in the critical stage and Sovteks in the non-critical stage of you BAT and see what happens. You might warm it up a tad w/out loosing the the clarity of the Sovteks. If that doesn't work try reversing them. A cheap experiment, especially if it works for you.
