So just over a week in and my tweeters are still working! System has been playing constantly at low volumes with the occasional blast at my usual listening levels.
Currently everything still sounds slow and still a bit flat. To be fair none of it has been used for almost 2 months! (my diy speakers using Audience drivers and PS audio Sprout have been getting a lot of love).
However, the imaging from the tweeters has never been better. It makes me wonder whether they needed some kind of service in any case. Raidho replaced the membrane in both tweeters to ensure they were matched and as good as new.
So still early days, though tweeters have lasted longer than before.
So I don’t think the issue has been robustly solved, and I think it’ll be a couple of weeks until I’m fully relaxed. However here are the options for the route cause:
1) Incorrect SAM profile effecting higher frequencies and causing ringing that fries the tweeter: as confused says, I’ve never heard of this before, though in the context of the correspondence with Devialet, they seem to be suggesting that SAM can have an effect on the higher frequencies, even if that’s not the intention of SAM.
2) Devialet repaired my amp without telling me: this actually seems plausible. It’s always been just the right hand channel that’s gone and not both tweeters. Repairing the amp without telling me would avoid taking responsibility (or am I being paranoid?)
Townshend repaired my speaker cables without telling me: this seems less likely as a repaired cable means a new loom of copper. Anyone with Isolda cables knows it’s impossible for those cables to look brand new once they’ve been moved around a couple of times.
For now I’m enjoying the music again. Almost forgot how much enjoyment I get out of a decent setup.
Thanks for everyone’s input.
Rock on all
