Why not stay with Tom Fletcher's sound?
When I heard the spacedeck (1997), I ordered the Mentor (now Dais). It is notably superior. Pear Audio is also a Fletcher design. I also have the Wave Mechanic power supply - another improvement.
IMO the tonearms were always a weak point, because of limited adjustability. The Trans-Fi Terminator tonearm also works superbly with NA. Don't know if it's still available - you could try.
