Hey @mofimadness
Well, I received the Golden Sound cones in a week. Much sooner than I was thinking.
In my current system configuration, the best/only place I can use them now is under my K&K Audio Trio Pre-amplifier. Also, I cannot compare between them and the BDR comes because of lack of space. So, until I make my system changes, I will only be listening to the GS cones verses the rubber feet in my wall unit. The Trio sits on a BDR shelf inside the MANA Acoustics wall unit.
I'm using the medium cones here. What's interesting is the difference in the design of the Mediums and the Supers. The Mediums have a "nipple" on the bottom/shelf contact end and a hollowed out portion in the top/component contact surface. I assume this design is from a lot of testing. It worked out well for me as, right where I wanted to place two of them in the back of the Trio were chassis screws. I was able to set the cones right over the center of the screws. The Mediums have no interface, compared to the Supers, which have a felt pad on the component end.
Almost through...I doubt if any of that interested you but being my first time using them and for others that have yet to use them, I thought it may be useful.
