As to your 'why' I answered above. Please reread my response- no need to repeat myself. I've read more than once or twice that damping is one of the key ingredients missing from older machines.
I contest that you are actually going 'up the ladder of turntables' just because they might be more expensive! High end audio is not driven by price, its driven by intention. So you can have a really expensive turntable that does not exceed the performance of a Technics SL1200G and in practice that seems to be pretty common. I've noticed that a lot of products in high end audio are not created by engineers so much as by audiophiles. Some have education and are familiar with engineering principles so have good products and others went to the school of by gosh and by golly...
In the end, you will find that you can't gaslight me on this one. No offense meant but I take my training, experience and measurement any day over what someone tries to tell me on the internet. The measurement side of this BTW is very repeatable and if you get it right the improvement its very audible. I can't think of why anyone would resist that!
