But if you've got a budget of, say $1200, then you might be better off (in terms of your audio experience) spending $600 to $700 on the table and $500 to $600 on the cartridge than $1000 on the table and $200 on the cartridge (depending, of course, on table and cartridge you are getting for that money).
Sometimes you can buy a $3000 turntable for half price.
You can also find a good deal on cartridges if you want to pay less than retail prices.
I don't understand how can you merit quality in numbers and where did you get your numbers from ?
Consider used market and your numbers will be irrelevant.
How can you be sure that more expensive is better for your ears ? For some people cheaper cartridges are better, I can argue about it too, but remember Denon 103 and its fan club ? It's $350 cartridge. I am not a fan of Denon 103, but you know how many people prefer that oldies over some very expensive cartridges?
Once you have a good turntable like Denon DP-80 whichis th best buy in my opinion (for example) you don't have to change it each time you're buying expensive cartridge, there is no correlation between DP-80 price and any cartridge you can buy. Tonearm mucst be matched to your cartridge, not a turntable drive.
