"I've played with lots of expensive gear so I know what I'm talking about."
I confess I haven't watched a lot of SG through the years, but it has been a lot of years, his longevity and popularity is impressive especially as he seems to reach new generations of followers/ The sentiment of the above quote in my opinion is also implicit (consciously or not_ in SG's authority as an influencer due to his already mentioned longevity.
He has and rightly so, his own self interest to protect from a commercial point of view. I'm kind of interested in what drives audio company's to design gear to a specific quality when there is a "whatever floats your boat" message being directed to consumers that invariably leads to a non-hi-fidelity outcome, so that instead of the industry offering (near state or0 state-of-the-art solutions to the user, they could offer inferior products with good slab of marketing to support it and a trust your ears mantra sticker on every piece of gear?
I'm not talking High-End, I've never really experienced that and have no burning desire to experience it, can't afford it and I don't bend towards that direction in any way.
When I look at the mid-fi offerings of Yamaha in their amplifier offerings it seems an ethos of quality is inbuilt into those products right from the conceptual stage? I get that feeling with Topping as well of recent past reading Amir's reviews.
But if we reward those making those efforts and can show evidence of it with measurement and analysis etc then I think that will go someway to prolonging "hi-fi" as a hobby more than a "whatever you like is fine" attitude.
Amir and a few others is to Hi-Fi waht the early Ralph Nader was to the car industry.
