It's now available @ HDtracks as below in flac format.
According to the explanation of the site, following is the difference between 2 editions.
Compressed (Limited) Albums - reduces the difference between the loudest and softest sound for playing music in noisy environments like cars or radios. However in this project compression was used very sparely.
No Compression (Unlimited) - is truest to the master tape, has wider dynamic range, and more impact.
So I'm sure that No Compression edition is enough to buy.
Regarding an instant download advertised @ official site for purchaser, I sent a question to Topspin customer support and they sent me the time-sensitive links for download 2 files, BOTR and No words (live in Glasgow 1979) in 320kbps mp3 format.
