I just ran across his "channel" last week when he detailed the Compact Cassette.
All in all I think he does a nice job! He mostly covers gear from the 70's-80's which is perfect for me. I did audio service in the mid-80's so a few of the units he as profiled I have worked on.
Personally I went to separates early on, I have never really owned a receiver. Never really embraced cassettes in any significant way either.
