So yeah, the Rumours double 45rpm I got was the Furnace 2024 pressing, though the description on Amazon said 2011, which would be Pallas and a Record Store Day special, so not bloody likely to get that new now. There was also a Pallas repress in 2020. But they should all sound identical anyways. Gave it a listen today and yes, WOW, big improvement over my Super Saver copy, not muddy but very warm and bassy. So bassy that I had to turn down the subwoofer to strike a balance. But that sound signature I think matches the decadent '70s atmosphere of the album, the heavy note weight really working for the music. Also listened to the CD I made that downsampled the SACD to redbook and that sounds outstanding as well, but very different. More clarity and definition, a lot less bass. I actually made a short vid that compares the two:
(Please pump it up.) There's a comment that the room acoustics make it sound horrible. That may be the case, maybe it's because it's a cell capture in mono, but still the differences between the 2 can be clearly heard. I don't have to choose between the 2 so I won't.
