Interesting analogy of transforming Mahler into Janacek (why not transform the Halle Orch/Barbirolli into the Czech Phil/Neumann...?). What verybigamp is probably hinting at is the analogy "transform the Deep Purple into the Deep Purple + London S O"... Older Koetsu had a beautiful sound at the expense of some db loss at freq extremes. Not that the fact ever bugged me when I used to have a Koetsu...:)
