Thanks for the welcome Steve, been a long time lurker here and haven't got around to registering so don't feel like a new member
All of the devices are on a properly suspended hifi stand (rubber mounts all round, spiked to the floor) so there is little or no vibration coming through.
It is also in a small alcove which may reflect some sounds but it seems more from the devices themselves as proven by listening to the individual devices close up.
The mod to the Linn seems to have worked and while you can hear the fan it is a lot smoother. Now the HTPC is back to the forefront, so I have been fighting with Abit's FanEQ to control a SS NT-07 AM fan.
All good fun,
