Does anyone have experience with the available upgrade package for the Eastern Electric MiniMax preamp? I'd like to know exactly what the upgrade entails, what others' experience with it has been, and whether they feel it was worthwhile. You can buy some nice NOS tubes for $200 (cost of the upgrade from Morningstar), and I'm trying to determine where my upgrade dollars are best spent, since I'm also presently in need of some decent ICs.
Thanks in advance,
Todd
