I connected 40cm of Canford Starquad SQ-6.5 to the output transducer of a reverb tank , screen to tank housing .
It works fine on line input (20kohms)into my SSL2 interface ,nice and quiet ,but lacks sparkle
when I change over to HI-Z(1Mohm) , which is also on balanced TRS it sounds better ,brighter and cleaner and noise is also low ,
but the cable becomes highly microphonic , to the point if I tap it with a screwdriver it makes a sound nearly as loud as the spring output itself , if I move the cable the strands of wire inside are audible as a kind of clicking and scratching noise ,
It doesnt cause any serious problem when the wires are stable and free of vibration , but its still not something you want .
I think I'll connect a 1Meg pot as a rheostat across the transducer so I can vary the matching impedence and see how the sound of the spring changes ,
theres no issue with the cable feeding line impedence 20kohms , maybe an intermediate setting somewhere in between that and 1Meg wil give a better compromise with handling noise in the wires .
