I've been self indulgent, didn't stick to my word, concentrated on the possibility to use the 30 day money-back guarantee and... I finally bought the downloadable version of full Audiophile 2025 (from Audiophile 2024). ($169 option in the table).

My download is limited on PG's end, not at home, but it is quite fast. 400...700Mbps most of the time. I already downloaded and installed 42% in less than 2 hours. I did not have any interrupted or failing download, I set 12 parallel downloads in a different drive and it seems to work quite well. I set a different drive because I install to a fast HDD, and de-compressing and downloading on the same drive was limiting speed. I did not have to check "download / install sequentially".

Now it says 48%, ETA fluctuating between 1h - 2h. If total time ended up being 3:30, effective average speed would be 386Mbps (48MBPS). So it is practical and effective, at least from Europe at this time of the day.
