Hi Frank,
Thank you for that very clear explanation. I have often read about your new music discoveries and your love of music does come through your posts. On your and Charles' suggestion I have gone to utube and watched/listened to a number of the tunes presented in this thread.
I do hope that there are not too many people who read these threads who are getting caught up in an endless upgrade cycle because they think it is the only way to audio nirvana. A number of posters (not necessarily on this thread) have not so subtly insinuated that if you haven't owned countless pieces of costly equipment you cannot have the knowledge to know if you have a good system. Lets face it, good equipment is astronomically priced compared to when we were younger.
The greatest tweak of all is to be able to be satisfied with what you have and as you said, enjoy the music.
George
