An update on Hyperion, which I bought a few recordings from recently.
tl;dr: poor site, great recordings.
Hyperion has a lot of great recordings: from their bargain basement I got some of the Howard Liszt series, James Bowman and Barbara Bonney doing Purcell, and good recordings of Messiaen and Martinu. The Isserlis Bach suites are still on my list.
The cheaper downloads are 5.60 GBP for the cheaper discs, less a discount if you pre-buy credit, so it works out as decent value. Navigating listings is hampered by the site designer's fondness for mouseover popups, which hid whatever you were trying to click on. The buying process is rather cumbersome, with details such as your phone number being considered required information. Downloading is not great: they don't offer zip files of the albums you buy, while their download manager uses Adobe Air and so is Win/Mac only. My solution is to use the Downthemall download manager (for Firefox), which downloads all the flac links on the page. Tracks which you have alread downloaded no longer have links, so it doesn't try to download them again; if you _need_ to re-download them, you can click on the button to get a new downlaod link.
The files are not usefully named (just a serial number); not a huge problem as you'll probably re-name them anyway, but it does make dealing with the files unnecessarily cumbersome. Meta-tagging is also suboptimal, with titles of tracks including the composer and work as well as the title of the actual track. Nothing that foobar can't sort out, but again we shouldn't have to. One plus point is the booklet pdfs, which are smaller than eclassical's, though they are well-hidden: they're not available from the download page, only from the album listing page.
