This is Panzerholz. Not mdf. Not Yuck imo.
Not yuck at all, rather gorgeous I might add. What record player is that?
I don't think marble goes well with audio gear.
I remember the B&W 2-way floorstanding Signature speakers with eaither black or white marble tweeters, not to my liking as well and they weren't that good.

Same with the Ether C if I may be honest. Special and flashy in carbon but gimme wood any time!
Not saying this Orpheus amp or the Ether C are ugly, I just prefer wooden stuff.
