While I've never been "tested", I have very sensitive ears and believe I can pick up frequencies over 20khz.
That is fairly easy to test:
What should I expect moving from MM to MC?
I understand it depends on the setup, so I'll start here. I'm starting small (in my quest for music Nirvana!):
I was considering moving from my Sumiko Olympia MM cartridge to the Sumiko Blue Point No.3 MC Hi.
Nothing but praise for the Blue Point in all reviews. But will I noticeably hear a clearer, fuller, warmer sound? Or is it a waste on money, focus elsewhere.
Thanks in advance!
