Agreed. Haven't tried their 6550's or EL34II's yet, but liked their other stuff and no failures IME. I really like their 6L6GC's also. I also didn't find any of the JJ's I've had dark. In general, I find them to have aggressive upper mid snarl relative to other brands (at least what I have), pretty tight and punchy, but gotta admit compared to almost any vintage tubes I've got sounds brittle, plastic-y and comparatively lacking warmth and the O word organic, but I like the way the JJ's are voiced/flavoredJJ pre and JJ power tubes in 50+ amps over 15 years and have had 1 maybe two pre amp failures and zero PT failures. EL34, KT77, E34L, 6550, EL34II. All JJs and not one failure. I'm not partial to any tube and not saying I'm a JJ fanboy at all, just that they work for me and they're cheap and available. I'll keep buying them.
I think tube failures are more related to just a bad tube off the line and even more often the abuse people put them through more so than brand. You buy a used amp and a tube(s) fail...how many times did the previous owner yank and insert the tubes. Some people swap incessantly and that can cause damage. Might not see it easily but that's gotta jack up the pins or where they connect to other internal components inside the tube. Shipping can easily damage a tube...they're relatively fragile.
And I don't get the JJ pres are dark/dull comments I constantly read. I can throw in a JJ pre and then swap to a tungsol, Chinese, or TAD 12AX7 pre and hear very little difference at all. And that's in many many different amps.
