Not sure what you mean by "off the cuff" here. Quatuor Mosaïques have been setting the standard for HIP of Haydn, Mozart and Beethoven for many decades and Naive (from France), likewise for many decades, have been releasing benchmark recordings of a wide variety of standard and not so standard repertoire.
The Da Capo label (see the Ruders Piano Concerto post above) has been the dominant independent record label in Denmark since the early 1980's.
I've had many of the Quatuor Mosaïques' recordings of the Haydn quartets in my CD collection for over 20 years and the ones I was missing I now have as downloads.
For the last several years most of what I've been buying is downloads in flac format just because of the convinience but my CD collection numbers around 5,500 discs so a lot of the music I post here is drawn from that.
Glad you're appreciating the stuff I'm posting about here. I'm very passionate about music and the recordings I post on various websites including this one are all ones that are special to me.
