Hmmm... long time since I looked up the mastering guys. Well, Kevin Metcalfe is one name that I remember. He did some stuff for Blue Room, like Koxbox and Juno Reactor. Probably many more. I did just a quick look at discogs.
Then we have Dave at the Townhouse and probably some other guys. Hallucinogen and Doof.
Someone... was it Ott? Let's check. Oh Kevin Metcalfe mastered the Mir album. =))
Yeah, the noise and crackles souldn't be there. That is annoying. But I would go for the big labels releases. Like Blue Room, Dragonfly and Twisted. They knew what they where doing. =))
