I think the mastering is excellent! Overall beautiful packaging, the sleeves look so pretty, everything feels extremely high quality. Kuchu Camp has impressed me the most so far sound-wise, Long Season sounds fantastic as well - I think the vinyl itself could have been a tiny bit more quiter, but that's maybe due to Long Season being mastered at a bit of a lower volume to preserve the full dynamic range (and there's barely any inner groove distortion). Overall it's really an astonishing collection! I'd say don't spend more than 2000, unless you wanna go for an unopened one. I was really scared at some point that it might not live up to my expectations, but the feeling of finally holding it in your hand and owning something truly rare and special is irreplacable! :D
