Interesting interview posted today on Primephonic's website with veteran engineer Jean-Marie Geijsen, whose work I know most recently from his recordings for Pentatone. (Personally, I don't think anyone these days does orchestral and/or chamber music in surround better than Pentatone and Sono Luminus.)
