FWIW I use new production JJ or Tesla (older versions) E88CC in my Woo headphone amp and my Raysonic CDP. Tonally they are a bit on the warm side of neutral and dead quiet in both units. They have good longevity and, best of all, are inexpensive. FWIW, if you want warm tubes of this variety I'd stay away from the Russians and I expect that any NOS tubes you buy that are both on the warm side and low noise will be a bit expensive. Caveat emptor. :-)
Help with tube choice
I need help choosing an E88CC/6DJ8 tube for my headphones/preamp. I know Siemens, Telefunken, etc, but I'm looking for people who use the E88CC/6DJ8 and have heard of tubes, im open to any tube, i only have a $125 budget for a pair.
I like a warm sound but not too warm, good bass, and magic in the midrange with a sparkle on top, don't we all want that? Shoot me the best tubes you use in this group; there are too many to choose from, and my budget makes it difficult.
Thanks
