New Turntable: Teres, Nottingham, Origin?

I've been leaning 3 different ways, if not more, in my quest to upgrade my analogue front end. I've read many threads here and searched out reviews, and I've narrowed it down to these 3--I think: the Teres 245 (or 255), the Nottingham Spacedeck, or the Origin Live Resolution. I would probably stay with the space arm for the Spacedeck, and the Origin Live or Encounter tonearm for the Teres and Origin. I'd love to mount the Shelter 501 as the cartridge, but I don't have the output on my phono stage (the Audion Premier).

Currently I have the MMF7 TT, which was by initial step back into vinyl. Although it was great for several months, and some records sound better than I've ever heard them, I can't help thinking about what I'm still missing. I know there are a lot of Teres fans out there, and I've really enjoyed following your passionate support for the TT. So please continue; I'd like to hear from you as well as anyone who has any advice, comments, suggestions to help me decide. How do the Origin Live and Spacedeck supporters feel?

I have a pretty good system, with Audio Note Quest Silver monoblocs, AN M2 Signature Pre, Zingali Overture 4 speakers, and Audion Premier Phono Stage.

Thanks, Bill
