    My preamp is in a ferrous case but that can be remedied...

    But surely stainless steel is also ferrous, or am I not understanding something?

    I don't listern to my sideboard just the item sat on it, but i do have a nice piece of Granite under the item to make it look pretty! thats all that matters aint it?

    Yes but it does'nt contain Iron hence non magnetic

    According to the British Stainless Steel Association:

    'Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium'

    I'm an arts graduate, and my last chemistry lesson was about 40 years ago, so forgive the stupidity

    Stainless needs the chromium to keep it's nice appearance.But at the end of the days it's not magnetic thats all that matters.

    There exists magnetic and non-magnetic stainless steel. Marco's Mana is non-magnetic.

    Indeed

    Btw, Steve, I didn't realise your preamp was housed in a ferrous case. I thought Anthony would've known better than to do that.....

    How long have you known, dude? You could've got it sorted the last time your pre was at Anthony's. You know the negative effect, sonically, of ferrous metals all too well!

    That's something you need to sort out A.S.A.P, as it'll be doing the sound of your system no favours whatsoever, despite it currently performing very well indeed

    I've been aware of it for some time and even discussed re-casing the preamp with Anthony at some stage. It'll be part of the next phase along with remote control operation.
