But the tape and the tape head are not mechanically coupledA piece of rock on a cable or on the house router affect the sound and they are not electrically coupled either...
An audio system is for me a UNITY emerging from the mechanical, electrical, and acoustical embeddings...The ears perceived much S.Q. than a single measure apparatus... This unity is neglected by most and by all measure apparatus indeed, but the ears can detect this unity ....I know that you know already that.... But this thread has silent eyes that listen.... :)
