I have been moving to more xlr sources as of late so I wanted a preamp with at least 3 xlr(balanced) inputs. I have a DIY phono , CD transport and dac so kits I assemble are doable for me. I found a Relaixed2 preamp and built it up. Relay controlled low gain opamp. I just finished the zircote face and applied the first coat of sea fin. Sounds great and remote controlled. The buffalo 3 sounds sweeeeet!
