RE: Marantz 8B with Bob Hovland Mods?

So far, the 8B edges out my Mcintosh MC30, MC240, MC60 and MC275, but not by a whole lot. However, I made an easily-reversable mod to each of the Mac amps that replaces the !2AU7s with 6CG7s. I did A/B comparisons (with and without the mod on each channel on each amp)and the mod makes a very noticeable improvement in all of the Macs.
