The OP asks why we don't see more reviews etc. Not sure if that means just on HH or in the wider internet space.
I think it is largely due to the toxic vitriol that still surrounds the subject in various places on the web. The dialogue that tends to follow ranges from subtly snide to outright aggressive. Just look at the comments that follow any article on the topic.
The best thing I find to deal with this is to just sit back and listen to music.
I remain impressed with what I experience. New releases seem a bit slower of late but sooner or later the Sony catalogue will launch. Game over.
