Charles,
I think it is one of the positive aspects of growing older and maturing. You come to know what you need and love from inside, and you stop seeking the affirmation as you said, from others. I still have desires for further refinements to my system, but again, they are based on my own positive experiences, not outside pressure (more apprentice platforms for example).
I would also like to take this opportunity to mention that I am finally changing out my beloved and somewhat modified McIntosh 2105 (still keeping it though!) for an 8 watt Audio Note Kits Kit 1 Tenth Anniversary. My speakers are 102db efficiency, and I have been considering this move for a long time. It was certainly influenced by you though, since I know and love your speakers, and over many threads I have seen that we share similar preferences. It is being professionally built by Audio Note Kits sanctioned builder, Pete Fulton, and yes, I did order a matched quad of Jupiter copper foil caps to replace the stock Mundorfs.
It will probably be another 3 weeks until I have it, but I have already waited for 8 weeks, so it's no big thing.
Thanks for generously sharing your experiences.
