How good is the McIntosh MC-2300 vs modern SS amplifiers?

I really liked the story John told where the band was playing Watkins Glen in upstate NY and some of the equipment got lost on the way. So they helicoptered one of the road crew to Binghampton where MacIntosh opened their factory on a Sunday to let them pick up some 2300's.

The Wall of Sound was really the brainchild of Owsley "Bear" Stanley (Curl, Wickersham, and others were brought in to make it a reality) and didn't last long for economical reasons. There were actually two base setups that leap frogged each other as the band traveled from venue to venue. When they were playing on one set up, the other was in route to the next stop on the tour to be set up and waiting for the band to arrive.

You can read Bear's notes on the Wall of Sound here:

If you ever saw the Grateful Dead movie which chronicled a 4 night run at the old Winterland in SF, you can see the road crew setting it up and hear the Wall of Sound in action. In one scene Phil Lesh is being interviewed and discusses the system and then demonstrates how it lets him play his bass as loud as he wants, which according to Garcia  in an old interview (and who also used a Mac amp for a while), was nearly as loud as his rig.

@georgehifi - sorry to say Roger won't be going down that path. He's just a curious guy that does a lot of research. When he heard Curl talk about the 2300's it got the better of his curiosity, especially given their use by the Grateful Dead with the Wall of Sound set up. So he looked into it and thought he would write about some of his thoughts and findings. If Roger was going down the path of building solid state amps, and he has built at least one I know of in the past, I'd be one of the first to hear about it.
