I am listening to the discs you sent, Dr Kildare, even as I keyboard this response. Incredible sound, better than I had hoped even after reading your self-rave! At 52, I have about 50% hearing loss in one ear, about 25% in the other, and it's a struggle to hear much of what I own on tape. Forget about MP3. This is crystal clear and other than having it beamed directly into my brain I can't imagine a better listening experience.
