Interesting question Bill. I guess the two main things that I have learned through this journey that I would do differently if starting over are: to be be more patient and to be content with simplicity. Don't lose sight of the goal, which is to listen to music. Sometimes our systems can become so complex that our systems overwhelm us, and we can't see the music for the equipment. I'd probably just grab a nice tube integrated amp w/ phono and forget about it.
Also, patience is a virtue. There is no rush to get 'it' now....wait a day/week/month/year and get what you want at a better price.
Cheers,
John
