Some old vinyl is just that... poor mastering, poor recording process, and worse, too many pressings per... I have a few direct disks that stun me regularly with their presence, detail, and sheer impact.
My secondary-favs are some digital recordings (there were a few great ones) that were then sent to vinyl with love and care.
I want a better streamer/DAC also, but how I listen to that source is vastly different than vinyl.
