I suppose this also holds true for the human body. I just find it more
noticeable in external equipment.

Thanks for reposting that link. I glossed over the original post.

Cheers, I'll do some toilet tests tonight with a range of trim
settings. I could not initially see the significance or difference
between the trim and input dials on this machine. I thought that
turning up the trim would effectively be adding a little extra input
gain, thus increasing the signal to (self)noise ratio. This does not
seem to be the case.
