Sherod, hope you are stil enjoying your new preamp. I admire risk takers and hope that your decision to make further changes did not void the warranty.
As for me, I will wait it out a little longer since the sound I am experiencing is musical and dynamic enough in my Condo, at least for now. I am playing at 11 o'clock and on rare occasions for guests its 12 to 1 o'clock. Lots of headroom to spare.
