Jack,
Good observation on this potential problem. I will keep an eye on this although I find the material very sticky and easy to apply so far its staying in its place.
The isolation base and the DIY tube trap I made improved things so much that the thought of using any other players at this point is not in my mind. I feel if there is any deficiency in the system it may be what can be described as the "more" effect whereby its not anything missing just more added when upgrading to the higher priced TRL players.
Alot of folks out there are struggling to get a particular sound out of their system. I have the opinion that having expensive gear does not neccessarily translate into synergy. For some reason the TRL player makes this effort easier to accomplish.
