Audiophile blues...

Phasecorrect, Alligator Records put out several anniversary compilations of the type of blues I believe you like. I can’t speak to your unforgiving system, but I think they’re worth a shot at the prices I see them being offered on Amazon.

You will thank me if you go here

Dorian Michaels album, Acoustic Blues in 24/96 from iTrax is stellar...

Robert Lucas's first 5 albums were recorded by Audiquest Cable using tubes and they do sound very fine indeed. All these albums are great slices of the blues genre.Layaway is my favorite with Chiropracter Blues. I love the line "Let me pop a bone in you baby." He was a very gifted blues guitarist,vocalist and harp player who Od on H a few years back.

Blind Pig also has a couple double disc compilations although with varying quality it is overall satisfying.

America's Roots musical is an LP that contains Little Walter, Howlin Wolf, Muddy Waters, Bo Diddly, Chuck Berry, John Lee Hooker, Sonny Boy Williamson, and Memphis Slim.
