Jadis with Telefunken 12AX7/ECC83 tubes


Hello,
After hearing few recommendations of Jadis users I have tried Telefunken NOS 12AX7/ECC83 tubes in my Jadis equipment. I put three tubes in lins stage of JP80MC preamplifier and two tubes in JA80 monoblocks.
I have mixed impressions. These tubes gave very good top end extension and sparkle. The sound was more transparent and some new details appeared. Also the soundstage improved in 3D depth. But some magic of midrange has gone. The Telefunken tubes pushed this a little romantic tube sounding set more into very good solid state set. I am not sure if the overall effect is what I require. Jadis is for to die for midrange and installing the tubes like Telefunkens pushes this set into a little different presentation. I am not sure if I end with these tubes and I am curious other Jadis user experiences with signal tubes rolling.

It has been such a long time since experimenting with tubes other than Tele's in my Jadis JP80 that I have mostly forgotten the differences. I do recall prefering the openess, greater delineation, and tauter bottom end begot from the Tele's. I have sampled Mullards, Siemans, GE, Sylvania, amperex and a few others, but always came back to the Tele's. I must add that I have had the preamp heavily modified by Great Northern Sound, having increased the frequency extension, top and bottom. The Jadis does seem to have lost some of it's golden beauty, but the presentation, to me, just seems more like real music.
