Best 12AX7 I have tried is the very rare and expensive CBS/Raytheon D-getter 7729. I also have a pair of O-getters that are close, but avoid the later CBS/Raytheon with the O-getter and 7729 etched in the glass. These last ones were actually made by GE and sound rather ordinary. Once I heard these I sold my Telefunken ECC803S, a nice tube but thin and lean tonally in comparison.
Rolled some 12ax7's recently...
Hi All,
I went through my supply of 12ax7's recently and found some goodies.
I recently compared Bugle Boys to Telefunkens in the phono stage of my pre-amp. Interesting (to me, at least). I found the Telefunkens to be nice sounding; very clean and clear, very nice detail, over all a very nice sounding tube. The Bugle Boys, however, were magical! WOW! Timbre was so much more apparent. The soundstage depth and width increased; especially the depth. The music seemed to come alive and glow. It was much more captivating.
I found such a dramatic difference between two high quality tubes very interesting.
I have yet to try 10m's, and 70's Mullards that I found. I will report when I do...
By the way, NOS Sylvania's sound nice in the line-level stage. All tubes reported are vintage NOS. I match them with my tube tester. And, I do not change the volume setting between tube brands tested.
Any comments are more than welcomed! I appreciate any information on your experiences with 12ax7's. The price of some of these NOS is incredible; I am glad to have these nice examples in my collection!
Cheers.
