No sorry not a reply to Claritas. But as a quick aside why not use Sennheiser HD800. All my music form early Baroque including organ to modern piano sound good to me.
What I actually wanted to report or ask a question about is that I have just been listening to my latest of about 8 recordings of Bach's Solo Violin sonatas and partitas by Christian Tetzlaff and noticed that the sound although from a single solo instrument moves from left to right and from front to back in unpredictable ways. Is this because the performer is moving about? I don't think I would notice such a movement if I were actually listening in a concert hall probably because I would be much further away which would neutralize small movements. It's a little irritating now that I have noticed it and listen out for it. Hmm. I am going to have to listen to all my recordings of this work to see if it is similar. At least a pianist cannot shove the piano around.
