One thing to add to my earlier post is to point out for those who maybe didn't know that Markus was also a very highly respected audio reviewer and columnist. His knowledge was in depth, technical and exceptionally broad in scope - pfm has unquestionably lost one of it's best brains. I learnt so much from him. I'll cite as an example a rather wonderful column piece for Stereophile he wrote back in Jan 2000 about the then emerging obj/subj debate (
article here). It is interesting to contrast his intelligent, balanced and informed words with what came later here from others of both sides. I should really stick a link in the site FAQ to that one! It is well worth googling around for Markus's audio reviews and comments, he was never less than interesting and informed, and as someone who once ran a Verdier/Shindo/VOTT system had an audio rig beyond what many of us have ever experienced. I'll miss him terribly.
