Jay seems like a nice guy and earnest. And I do like the gear pron aspect of his channel.
On the other hand, I find him over-serious, always delivering stuff like it’s almost like he was up all night contemplating how he’s going to break the important audio information to the audience. I personally wouldn’t take audio advice from the guy as I think he’s quite far down the rabbit hole. But on the other hand I have little doubt he’s had some great gear and his system probably sounds amazing.
