Unmodified this is not a spectacular combination. However, Musical Concepts sells modification kits for the Hafler electronics. These modifications the replacement of most of the caps and resistors with high quality types. (pp,ps caps;1% tolerance resistors). Many values are altered. The change these mods make to the Hafler equipment is nothing sort of amazing. The sound had a much more alive quality. Soundstaging and tonal balance is much improved. The M220C kit for the Hafler 220 is priced at $175. The combination of these mods on the Hafler electronics is hard to beat. You should be fairly good with a soldering iron to install the mods. If you built the kits yourself, this should be no problem. Steve Castillo University of Illinois Electromagnetics Laboratory !uicslvax!mnt!spc
