Anyone enjoy their amp's sound more than music?

The more my amps sound like the music I hear(live), a couple times a week; the more I enjoy them. Just installed four Deuland CAST-PIO-Cu coupling caps, in my mains, to get a wee bit closer.

Hello Mr R- I'm using them as coupling caps, from the plates of my dual triode driver tube, to the output tube grids(one per phase). They are .22uF/630V(in my Cary mains). A side note: It's said that the CAST/stacked construction(of the Deulands) obviates the need to orient(what would be) the outer foil lead, toward the lower impedence, for least noise. I tested mine(before installation) and there was a marked difference in noise levels, when leads were swapped to ground. My apologies, if we are seen as hijacking this thread.
