amg56, I apologize if I insulted you. I was (and still am) genuinely confused by your post. You still haven't said why you are unhappy with your cache of current turntables.
I don't know anything about your Allaerts MC1 cartridge, having never seen one. The manufacturer doesn't publish compliance (resonance frequency) so it's not known if that cartridge is a good match for the MA-505S tonearm. It's hard to believe not - the MA-505 is an excellent tonearm and as close to universal as is possible. But they do require periodic maintenance and careful setup in order to sound their best.
But enough about that. Please tell us what you are trying to achieve? An endless set of comparisons of vintage turntables is pointless. What's not working for you and/or what are you hoping to improve?
