The Ediswan CV5358 might be what you're looking for. I used a pair for a while, and they were certainly smoother than the Seimens 7dj8's which replaced them. Check Joes Tube Lore for more details.
Looking for a smooth sounding 6922 variant
Hi folks. I am currently auditioning some cables and am starting to suspect that a bit of higher-frequency harshness (fatigue, just a bit) might be due to something else in my system. Could be anything, including the cables I'm auditioning. I wanted to eliminate other causes, and so I'm looking for a pair of 6922' variants to put in my VAC Signature IIse to smooth out the higher frequencies a bit. I think I've got telefunkens in there now. Can I get some recommendations? Perhaps Mullard makes a nice 6922. Please answer with direct knowledge/experience. Thanks.
