Fbi, Nsgarch, I have Svetlana 12AX7's in my modded Jolida JD100 CDP, and am now thinking of trying the 5751's. Nsgarch, you mentioned the 5751'a are spec'd at 70%-80% the gain of the 12AX7's. I'm presently using a set of Rothwell 10db attenuators with the Jolida to help with the gain. Sounds like the 5751's will help a little more in that respect.
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.
