In my opinion, Codex 6 and the "Super Deluxe Edition" of Are You Shpongled? have a very good sound quality but the remastered edition of Tales Of The Inexpressible sounds a little bit worse. I use a Technics SL-1610MK2 with a Technics 207C system.
By the way, the Skylon album by Ott is also still available:
