I've worked on a couple of stereo tube amps, one was a Mac. Never again as was pointed out, the weight is killer.
If you wish to re-tube the Mac, that's 8 power tubes. There's an old adage. SS amps will require x times the cost of a tube amp for similar tone. Dunno if this still exists tho.
Mac has been bought and sold:

As for making a decision, if possible, work with a local high end audio shop and take them home and try various amps in your price range. Take note: you can't put a review up to your ear and listen to it. As mentioned, there's a synergy that occurs with your equipment and with your room.
