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


John Curl gave a most informative talk on the Wall Of Sound used by the Gratefful Dead. He had a lot to do with the speaker end of things but had not much to say about the amplifiers which left me curious about them. 

I pulled up the following manual and schematic and suggest anyone interested in advanced circuit design of the 1970s have a look .. http://www.tubebooks.org/file_downloads/McIntosh/MC2300.pdf

Read this https://en.wikipedia.org/wiki/McIntosh_MC-2300

and this  https://en.wikipedia.org/wiki/Wall_of_Sound

There is an earlier discussion about autotransformers where some call the autoformer a "band aid" for a poor design and others slurs. However this is a fine amplifier, virtually bullet proof, and used in great numbers by a band known for its incredible sound. 

I welcome any comments and questions.
