For you guys who have done your FrankenZeros already:
PP and I both noticed that as the PIO caps mature, the soundstage can change drastically by going from narrow to super wide and back, and the upper highs and lower lows, can come and go as well. Since we had the exact same thing happen with our FrankenZero's, we consider these traits to be normal growing (maturing) pains. They will pass, the closer you get to 250 hours, and maybe a few more hours in some cases.
Thanks for the kind words guys! I can't stop listening to my FrankenZero! Once it is completely matured, testing it in different situations is a great deal of fun, because of its superior SQ. It has turned all my headphone amps into super headphone amps! Its analog output is fantastic for speaker systems too!
All hail the FrankenZero! Just like Frankenstein, he is the sum of all his parts, ready to scare away unwanted audio properties! What a monster!
Egor, hand me the last by-pass cap!
OMG, It's alive, It's alive! Hide the women and children! Burn the village!
