That Bushmaster Earth Terminal

[MartinT]

I was sorting out my phono earthing arrangements earlier, and marvelling yet again at what a difference to sound quality it can make, when I suddenly thought about that slightly mysterious ground post on the back of the Bushmaster. Stan doesn't do anything for no reason, so he must have thought that his DAC coiuld benefit from an external earth connection.

So I tried hooking up a bit of green wire from mains earth to that post and have been listening to it this evening - mostly the Olympic broadcasts from my Sky HD box, I have to say. I can't be sure, but I detect a small improvement in detail and presentation similar to, but less pronounced than, getting the phono earthing right.

Has anyone else tried using that ground terminal and what did you hear?

Stan - do you want to comment on why you implemented an earth post?
