I bought the album on Linn download (24/96 FLAC converted to AIFF using XLD) and compared it one after the other with the 192kbps version I had already.
Couldn't tell a great difference between them although the 24/96 version sounds a bit more refined and you could only smell the ganja with the 24/96 version
Will I be rushing to buy more 24/96 material? No, because I don't think there is a huge difference between 256kbps (or actually even betweeen 192kbps) and the 24/96 version takes up 130MB per track vs approx 6MB per track on a 256kbps version and I use a Solid State Drive (because it is completely silent and fast) so space matters.
I think, on balance, lossless at around 800kbps is probably indistinguishable to my ears from higher res. versions so that's probably the extent I would go to.
In any case there isn't much on Linn records I would want to buy.
Thanks for the heads up though Cno, gave me another chance to play around and experiment and I don't regret the purchase at all.
