re: Steve Guttenberg, John Darko, Jay's iyagi
In my opinion...
the first two are entertainers, not reviewers
Erin's audio corner, Zero Fidelity, A British Audiophile are reviewers. Jay's iyagi to a large extent. They adhere to all the basics, to be independent, disclose what's subjective and objective, disclose the method, flaws of the method, metadata, all that.
New Record Day as well and cheapaudioman on good days.
Darko is regularly made fun of by the hifi community, he is all over the map, contradicts himself a lot, makes baseless conclusions, comparisons, etc. But he is fun to watch.
