Mike, are these the Sonicap/Mills upgrades in the crossovers you are talking about, or were these crossovers upgraded farther than what is offered on the GR Research site?
I appreciate the answer, I am currently not working and selling a camera lens to finance the Kit from GR Research.
These have Sonicaps, Mills resistors, Alpha air core foil inductors, Sonicap Platinum by-pass caps in the tweeter circuits, Miflex KPCU by-pass caps in the woofer circuits, tube connectors, and are lined with No-Res. The Platinum by-pass caps are no longer available so I am currently using the Miflex KPCU caps in both woofer and tweeter circuits.
