Actually, Eldarford..yes. When a tuba plays a 60 Hz. tone, it is resonated on the box and in the string of the violin...that's why playing "in tune" is so important when playing in an orchestra... a tone that "rubs" against the harmonic tones of the rest of the players makes people wince. That is also why most violin concertos are in D...because the other strings will resonate and strengthen the open strings...E, A, D, G,. In stereo system, you want NOTHING to detract from the original event...it's not like playing the violin since then you are constructing your own event...the event becomes truth. That's the meaning of high fidelity...truth to the original event. Hum and noise ain't an original event.
