Sure electronic music also sounds good on tube audiophile equipment but I think the tube sound compliments acoustic music to the point where it can be better appreciated.
Years ago I bought an Ultra Lounge CD because it had the kind of music my father enjoyed listening to. It sounded OK on my solid state equipment but it seems the tube equipment really brings it to life. Since then I've added Miles Davis albums and some classical recordings to my collection.
I've even started watching reruns of the old Peter Gunn TV show which focused on cool jazz as part of its appeal. I'd like to find so more old jazz with good female singers from that era. I do have one Billie Holiday CD but I'm sure there are more I need to research.
Any suggestions? ...Thanks....Blake
