Catalogue is better than the late, lamented Primephonic. Opera is still not to snuff (probably because all the space it occupies and the size of the audience), but I have a heck of a lot of fun going to, say, a Beethoven Middle Period Quartet, and choosing from a veritable cornucopia of performances to click on. The website operates briskly and accurately.
Oh yeah, one other slight problem. My Firefox refuses to insert an Idagio icon on its home page. I have to do a search for Idagio if I want to access it. Of course, after tapping in an "I", a "D" and an "A", Firefox figures it out.
