I got a "temporary" trade of the Rx Mk3-B for my Continental V3 and I am impressed. I noticed the mk3 expanding the soundstage further and the bass tightened a little bit. The only thing that irritates me is the channel imbalance. Full volume on Low gain is not enough for my Westone 4R unfortunately as I listen to music pretty loudly. Medium gain is ok but my listening level is to the point wherein a little turn of the volume down would give channel imbalance. Other than that I am enjoying this combination with my CLAS.
