Danny’s video was a response to Jay’s Iyagi’s video and clarified or corrected things Jay was saying. I think Danny made it very clear that when people send in a speaker to him, they are doing so because there is something that needs fixing and he is looking for a parts solution and he is not redesigning the speaker. He also clarified an issue Jay had with GR Research’s own products in terms of bass heft.
I’ve found interesting stuff on both Jay’s and Danny’s videos although generally, Jay is reviewing products I’m not that interested in since I tend usually to more boutique stuff where the manufacturer isn’t sending stuff out to YouTube reviewers.
There also is (in Danny’s video) a little gig on the ASR method.
