Absolutely. And I'll be the first person to tell you not to buy based on one review and especially not a Z review. He's the king of hype. BUT, I do trust him to point out any glaring flaws and it's nice to have another data point. Not everyone ( myself included ) has easy access to various brands to be able to audition them.
To be honest, I have doubts about the way he tests hi-fi components, his system is an absolute mess of wires But if it works then it works. He's an entertaining watch, but I liken him to the Angry Photographer (infomous in the camera world), certainly not John Darko (he has the attitude you get what you pay for at any price level) pretty much the only YouTuber/reviewer i trust more than any other.
And not to be rude but there's always a way to test gear I live in a very small hamlet with nothing around for miles and i have a good relation, I've fostered for many a year now with a Scottish dealer and they send stuff for to me test, at no cost to myself and im 600miles away from them. You may have to lay a deposit the first time or 2 but eventually, they will send with no questions asked especially if you have bought a few bits. Its got to the point where I only test/audition products at home and if can't I move on to the next dealer, I don't give a dam what it sounds like at the dealers, especially speakers.
The old ways need to die, dealers/manufactures need to be more furth coming if they want to compete with the internet in this day and age. Have stock that people can rent for a week/ month or whatever.
