Honest question about cartridge vs. turntable performance.


I’ve been a vinyl lover for a few years now and I have an ortofon black cartridge setup with an mmf 5.1 turntable with acrylic platter and speed controller. My question to all the vinyl audiophiles out there is this. How much difference does a turntable really make compared to the cartridge? Will I hear a significant difference if I upgraded my turntable and kept the same cartridge? Isn’t the cartridge 90%+ of the sound from a vinyl setup? Thank you guys in advance for an honest discussion on this topic.

You guys are right; I apologize for my part in digressing from the real topic of the thread. To the OP, I would say that my experience over the last 10-12 years, with running up to 5 turntables using 5 different tonearms with dozens of different cartridges is that you should consider the cartridge and tonearm as a unit, a closed system.  The SQ from any given cartridge, no matter how expensive or how cheap, and no matter how it transduces physical motion to an electrical signal (MM, MI, or MC), is highly dependent upon the tonearm/headshell into which it is mounted.  Mating cartridges to tonearms for optimum results has in my experience been a hit or miss affair (after one has done the homework to make at least a good mating), in terms of max results, but you can get "good" results by thoughtful matching done on an empirical basis.  After that, turntables each have their own character which seems to remain fairly constant regardless of the tonearm/cartridge mounted on a given one. Also, to a large degree, where a tonearm has exchangeable headshells, you can manipulate the result by experimenting with various headshells.  So, I never think of the relative importance of a cartridge and a turntable per se.
Thing is, turntables don’t wear out after 1000 hours. Neither do tonearms. So look at TT, tonearm, and cartridge costs over 10 years.

For the record, I had a 10K belt drive TT. Then I built my DIY air bearing TT. Same tonearm on each table. The air bearing TT sounded far better with a budget cartridge than the commercial TT with a higher end Koetsu. Wife agreed. But DIY TT + Koetsu = heaven.

Also, that Koetsu takes real trouble to set up optimally, and a lesser tonearm can’t do it. It's a matter of alignment, which requires both stability and the capacity for fine adjustments.

Finally, before you spend big bucks on a cartridge, try to make sure that your stylus wears slowly. That means ultrasonic record cleaning and strict record hygiene. I do both, and my Koetsu stylus has minimal wear at 1000 hours. If that’s too much trouble, then definitely do not spend serious money on a serious cartridge until you win the lottery.
I agree with Lewm about the cartridge / tonearm combination. Also, that TT's are pretty much independent of either.

So why not spend the money where you can be sure of good results? That is, the TT.
