Not necessarily the job for this review, and not asking Vintage Flaker to do it but me personally I'd be interested to know if objectively this sound as bad as it looks. I think we still have a long way to go in the actual real world assessment of what really matter in measured fidelity and what makes no difference or differences that don't translate in actual real deficit to the enjoyment of music. I mean, me I know, objectively, that the little BT speaker I own sounds like crap. It's obvious. I know that 64 kbps mp3 sounds like crap, it's obvious. This? I don't know? Does it? I think it's interesting, for me at least we just have some very theoretical transparency thresholds, but what if manufacturers are chasing performance metrics that objectively in real world don't matter at all?
I am not trying to say here that there something magical with distortion or that it's an ok product or that it's ok to falsify specs. I also agree that a listening assessment is fundamentally flawed, but if no one ever get a shot at it, there's a big empty field to explore I feel.
Blind listening studies are very sparse, little conclusive, are about tiny difference spotting. It is interesting to me that something very flawed can sound good to one's ears. I mean, we all know bad, but would I hate the sound of this? I don't know.
