Wish I could give a good update. I think I'm trying to do too many things at once......
I was nearing 300 hours on the new tubes and everything was starting to come together. The new tubes were definitely
different, and overall an improvement. I was hearing more music than before. When there were duets, it was easier to hear each voice. The instruments were sounding better - more natural.
I think the greatest improvements were in the areas of soundstage and micro dynamics.
Everything really starting to shape up.
Then I changed the settings of the internal crossovers on my LS-6'es. BIG improvement in bass. Mid bass MUCH better, better low end extension.
............ BUT.................
Where did my soundstage go? Depth has vanished!
Asking lots of questions on other sub forums, and I think a serious re-do in setup/room treatments is about to begin.
This truly can be a frustrating hobby.
