Turntable versus tonearm versus cartridge: which is MOST important?

Dear @lohanimal  : You participated in the next thread where along it several opinions were discussed.

Here my asumption/premise was and is: " everything the same ".  Your point is not what  is under discussion but as always welcomed.

@rauliruegas  I did raise the trough and the vintage bargain as curveballs - just for a bit of fun - and it may well have digressed.
IMHO if it is based upon how one splits the budget (and i am going to do it on the basis of new equipment) turntable, then arm, then cartridge. My logic is based upon the law of diminishing returns happen further up the turntable ladder - then the tonearm - then the cartridge.
Cartridges are a funny thing as everyone will know because important though it is - it really does change the signature sound profoundly. Not just that but even new there are some really great bargains (relative) out there which have certain skills that exist regardless of price.

Agreed, everything is important. Sound fidelity (like a chain) is only as good as it weakest component. The best table and tone arm has no chance against a marginal cartridge. As such, a magnificent cartridge has no chance against a marginal recording... There is an app called turntabulator that will check your table speed. Some fine tuning on tracking and weight can make a huge difference so my choice is use the best cartridge you can afford. Much more to say on this subject but for another time.

Nice try. Freebie rubber power cords are absolute crap. If I swap out my Moneoone Supernova for freebie rubber crap it is obvious. But it doesn't bring my whole system down to that level. It is worse, obviously worse, but still much better overall than "its weakest link."  

A system is the sum of its parts. The weakest link may be the smartest place to look for improvement. But it is not what determines system performance.

The opposite of what many of us have said. Based on experience. The best table and tone arm will make a marginal cartridge sound incredibly good. The best cartridge on a marginal table and arm will only let you hear very clearly all the faults that made them marginal in the first place.

Spend $150 on each the TT, tonearm and cartridge. Then put the remaining $9,500 into a cable! Shell out another $1k on fancy interconnect nail polish coating.

Case closed. Problem solved. 

Or rather than an unrealistic approach this of all or nothing mentality, why not use a more balanced approach and allocate your budget so that each component gets consideration?

Lastly, why is no one mentioning the phono preamp? This is as much a factor as the rest. Especially if you are using a cheap $50 phono pre built into an integrated.
