Kirk,
Glad to see you followed up by posting the question here. Sounds like you've narrowed it down to 2 great TTs.
When I suggested the Spacedeck/Spacearm to you, I didn't go into detail as to what led me to that turntable. These are my own opinions distilled from combo of personal experiences and what I've been able to absorb here & elsewhere from the likes of those commenting here before me.
- No suspension often = better performance in this price range. IMHO, when designing around a budget, designers must make compromises. I prefer to see more of the cost go towards the components that contribute more directly to overall sound. Yes, this means I need to have a solid setup(in my case w/Neuance shelf on a heavy Billy Bags rack), but that appoach makes sense to me.
- Puny motor/no switch, novel approach. Some have said that the "Nott motor isn't the greatest." But, since it doesn't need the to power to get the platter "from 0 to 33 1/3", it makes sense. Ergonomics of the manual start are a kick, too!
- Character of the "Nott sound": Big images wide & deep, emerging from a black background, plenty of PRAT, and a natural timbre. Perhaps not the ultimate in dynamic contrasts, nor the most transparent compared to some other tables, but always musical, never calling attention to itself.
- Good engineering, lousy marketing: the value 1-2 punch ;-)
As I haven't heard a Gyro SE, can't comment on it, although I did enjoy listening to older Michele's that I've heard. Keep us posted. Cheers, Spencer
