Well, Congrats, Joseph...I am glad you find one...they are supposedly a very, very nice amp....your cans deserve it
Everybody getting their new amps is making me impatient in getting mine.....been waiting for months now......breathe deep....relax
In my experience when putting the G cushion on any Grado, that did not come with it as stock.....it did just what you are looking for....less bass and increased soundstage, you should be good.
Sorry to hear this, worms.....hopefully that will make a fast and healthy recovery and be home soon!
