I think you messed some things up there, buddy. Oluv prefers a rather bright signature in my opinion, which is exactly the opposite of what you discribed. He critisized the Harman Target for having too much bass (which is ok to do, as especially the bass is highly determined by preference), and adapted “his” version of the B&K Optimum HiFi-Target, which is kinda the opposite of “dark” and “warm”. And what do you mean by “detail”? A boosted treble response? Maybe your preference is “VERY unorthodox”?
While I disagree with Oluv on a couple of issues and I sometimes dont like his kinda “aggressive” style, I still think he is a honest guy who just aims for the most natural sound reproduction. I can also understand him in some way, as there is a lot of crappy audio hardware out there which is still getting a lot of praise and hype by “audiophiles”. This can be chastening and I have gone through this too.
But I generally dont care for all this “reviewer” stuff, as I dont find it helpful to try to discribe an audio product like a bottle of wine and I think most of these reviewer guys are just paid or have other incentives, so for me this isnt really helpfull at all. There are way worse reviewers on YouTube I have seen (with even more followers).
Have a nice day.
