Hello Frankie,
Welcome to WBF!
Ultimately there likely is going to be a significant leap of faith involved in selecting a new turntable. It is unlikely that you will be able to compare, side-by-side, the Bergman Galder + Odin and the Air Force Three Premium + Graham Phantom Elite or some other competing combination.
Even if you could make this comparison you still would not be hearing, apples-to-apples, the Bergmann Galder by itself versus the AF3P or some other turntable by itself. For that comparison each turntable would need to have the same tonearm and the same cartridge, and both would have adjusted and aligned the same way on each turntable.
Only because there may be no better options in the case of turntables, perhaps reviews by Michael Fremer are more probative for turntables than is the case for other components.
How does one talk oneself into making such a leap of faith? Does one learn about turntable technical design? Does one learn about direct drive versus belt drive versus idler, and select a theoretical preference, and then look for turntables which use that drive system? Does one go by the visual and aesthetic machining and finishing quality of the product? Does one go by how it feels when you play with it and operate it? I think all of these non-scientific, non-audition-based factors get baked into the leap-of-faith cake.
The good news, for you, I think, is that the Bergmann Galder + Odin and numerous alternatives mentioned here are wonderful sources.
Specifically, I would encourage you to:
1) Read carefully the reviews by Michael Fremer of the turntables you are considering.
2) Read about various turntables in threads here on WBF discussing them.
3) See and hear them at dealers or at friends' houses and play with them and see if one of them attracts you in some way.
4) Assess which dealer will take seriously initial and ongoing responsibility for setting the turntable up and for aligning the cartridge. I feel that there are very few truly expert cartridge alignment specialists out there, and without proper cartridge alignment and turntable set-up you will not be realizing the sonic capability of which any of these vinyl replay set-ups is capable. Alternatively allocate in your budget a plan for somebody like Stirling Trayle to visit you on-site and adjust your cartridge expertly.
