Brent Jessee mentions 50 hours or so, of listening/burn-in time, as a norm.
That's been my experience, as well.

BEL E88CC/6922 tubes - what can I expect?
Lately I've been tube rolling 6922s in the gain stage of my Sonic Frontiers Line 1 preamp, and considering trying the BEL E88CC/6922 from Upscale Audio. Since Upscale doesn't provide explicit recommendations on tubes and these aren't available other places, I wanted to see if anyone has opinions on these, or maybe there are other tubes I should try? So far have tried
- Svetlana (came with preamp) and these were dull, lifeless.
- Electro Harmonix gold pin - ok but kinda boring compared to others. Currently using these in input position.
- Amperex white label - fun but a little too tubey.
- Matsushita - I really like these but also a bit too much tubiness over time.
- Mullard - favorite so far, just sound right.
- GE "smokies" - still evaluating.
FOMO is creeping in as it looks like Upscale's inventory is dwindling. Any opinions? Other tubes I should try?
System - Thiel 2.3s, Krell KAV amp, SF L1 pre, bel canto 3.7VB DAC, decent room treatments, always think the higher end could get better if less sibilance/reediness.
Thanks!

The only fault I could find with the pair of Amperex USN/CEP 7308, mid 60's, that I tried, was their slightly warm coloration. Other than that: everything was lovely. Seems we may have the same tastes, regarding presentation. Try to find a NOS pair of Siemens CCa, grey shields, external date coded, from the late 50's or early 60's. If you can locate a pair of E188CCs, of the same description, they offer almost the exact presentation. Bet either would suit your aural palate, to a tee! Some history: https://www.tubemuseum.org/ProductDetails.asp?ProductCode=SH%5FCCa%5Fsingle I found those later CCas, with the internal date codes and silver shields too bright/zingy, for my tastes. |
