Awesome. Here are the tips I use:
STTC-126 (SMD passives and IC pins)
STTC-025 (also handy for SMD passives)
STTC-037 (handy for leaded parts)
STTC-036 (handy for larger leaded bits)
STTC-117 (wide chisel for tabs, DAPs, etc.)
I do recognize that they're not all the same temperature. I received about ten different tips with my MX-500 when I bought it. If I was to get a subset of those tips, I'd go with the STTC-026, STTC-037, and STTC-017 (or 117). The first digit denotes the temperature (0 = 357 C; 1 = 417 C AFAIR).
I'm puzzled by the ground lifting doing anything. With the resistor tweak I suggested (i.e. plucking R46 and R115 off the board and connecting the "inner" pads of those footprints together with either a 0 Ω resistor or a piece of wire), the ground of the HP-1 is already lifted. The only thing I can think of is that the XLR Pin 1 is grounded to the chassis (as required/strongly encouraged by AES48-2005). Maybe your source isn't so fond of that. That'd be odd, but I suppose weirder things have happened. It's good to hear that a ground lift clears it up, though.

Thanks for the part numbers. I managed to do all the remaining soldering with a STTC-136, though the relays were a little tricky. The STTC-190 tip I thought would work for smaller pads was just absolutely no help. Look out for a 8x2 Preamp order from me tonight I'll probably order the tips from Mouser at the same time as those parts.
The HP-1 is really an amazing headphone amp. I blame it for for my recent Focal Utopia and Chord DAVE purchases
