Aurios bearings
I've had a set of these on shelf for several years; I tried them under the Roksan and they made no difference that I could hear, so I put them on side meaning to sell them but not getting around to it.
I noticed that Martin T uses them under his SACD so out of idle curiosity I put them under the Meridian transport. They make a significant, positive difference, and I'm kicking myself for not trying this sooner!
