Thanks David. I actually spoke with John H. and we talked about the upgrade path for my amp (D-140i) that takes it to the D-150B status. I'm eventually going to send it in for the upgraded circuit boards and at that time, I'll also replace certain caps and resistors.
In the meantime, I'm wondering how well this amp will respond to other power cords, replacement of fuses, and maybe some ERS cloth. It already has upgraded Edison Price binding posts and chasis dampening material.
