xcskinbike,
A properly cryo'd outlet (such as the Virtual Dynamics you purchased) should make what ever is plugged into it sound like it got an injection of steroids in just about all sonic directions. I think it is possible that results could be dependent upon the components in anyones system. I would believe that you would have heard a difference even if you did not try the other outlet.
How long have you used the Virtual Dynamics outlet for? Since it probably was not burned on a cable-cooker it could sound harsh and undeveloped for several days to four weeks. The outlet needs to be used 24/7 until it's sound developes.
If you think its snake oil, I'll offer you $15 for the VD cryo'd outlet!
