BV to IH and HvM V4-1

Vol 4-1 Both Ian Hegglun's article (Towards Reconciliation of Measurements and Listening Tests) and Hans van Maanen's Guest Editorial (The Case for Subjective Listening Tests) in Vol 4 drew comments and some interesting additional information from prolific author Burkhard Vogel. His comments and the replies by both Ian and Hans are here. The reply from Ian Hegglun also contains several corrections to his Vol 4 article. (Note: updated 1 Jan 2013)
