With my new system, I've developed an appreciation for mono recordings. It's jazz for me: Ben Webster's Soulville, Monk and Coltrane, Freddy Hubbard.
Mono used to be a deal breaker, but now I totally dig it. In some weird way, its simplicity is sometimes a relief. And its every bit as musical.

I can't speak about downloaded music. I haven't gone there. ("just say no" to lossy formats!)
