I don't know about top ten, but, I have heard good sound from systems using the following:
Emotive Audio Epifania (I own one of these)
Aldo preamp (custom built preamp from a Western Electric rebuilder in Italy-transform inputs and outputs. I also own one of these)
Veloce (I heard a nice system at a show using this preamp)
Audionote (uk) M-10 linestage and phono preamp (you need an extra room to house these monsters with their multiple power supplies)
Audionote (Kondo) M-10 linestage (I auditioned Stax Omega II headphones on a system with this linestage and bought the phones. They have NEVER sounded as good as when played through the Kondo).
