The fact the guy above no longer owns the table tells me he is deaf.
The "fact" that someone would make a statement like this indicates a lack of comprehension and critical thinking skills.
The 7.3 is a nice entry level table. I'm glad you enjoy yours. I enjoyed the 7.1 when I had it, but you don't have to spend a lot more money to get significantly better sound quality out of your turntable, in fact, you may do better for less money.
the technics has an inferior tonearm and way less isolation from vibrations if any
That's a head scratcher. Like many poor misinformed souls, you see the SL 1200 MK2 as a "DJ table". That is understandable, since it saw wide use in that application. And why was that? Besides the accurate motor, it had excellent isolation characteristics. Reducing acoustic feedback and resonance were design goals. It was never designed or intended to be a "DJ turntable" though, it just happened to be the right tool for the job. Try using the 7.3 in a club environment.
The mmf-7.3 can stand up to turntables 2 and 3 times the price!
Name a couple.
you do not need bigger feet
The feet on that table are pretty cheap and it doesn't have much mass. Have you tried putting better feet on it? Or any table for that matter?
The point I was trying to make was that by the time you make a bunch of incremental tweaks like mats, cables, etc. you would have been better off just buying a better turntable. The 7.3 is no slouch, but it's not worth doing a bunch of tweaks to. It is good enough to put a better cartridge on. That's going to be the thing that will improve its sound the most.
