For my Galaxy, everything went up a notch with Rhapsodio's RSD Silver Mk3 (currently on their FB cover picture). But I am not sure about the synergy with RTi1.
Hey there. Sammy mentioned the mk3 to me and I was considering it as well. Is this the $450 one? The one on the FB cover looks identical to my regular RSD Silver I just bought. But I assume I have the mk1 or mk2 or something, can't quite tell. It's a pretty cool, analytical cable. I think he said the mk3 is warmer with better bass? Thanks for any insight!
