Oh, most of my shellac listening was to one speaker, so I know whereof thou speakest, and yes it's something else.
I just no longer seek "the holy grail" sonicswise. I want a system that makes most of my material sound really good, and with my CD/SACD sources and Decware speakers and amps and the good cabling and power conditioning I have I've achieved that goal. For me it's about the music far more than the sound itself.
Handling and archiving and using a collection of shellac discs requires more patience than I have! Kudos.
Document certainly isn't the ONLY label doing pre-war music, let alone the only one doing "race records" on cd, there are Yazoo and a few others for that genre. I'm much more a fan of jazz and hot dance and there are a number of good labels for that, my favorite being Jazz Oracle. I have every one of their releases, most with restoration and mastering by J. R. T. Davies, whose work I appreciate.
Anyway, I think you'll really enjoy the Integrated. Enjoy the long wait.
