600 - 800 hours is about as far as I'll trust a well aligned elliptical with my records..:scratch2:
As for the cartridge cost relative to turntable cost equation...
I think the older British magazine recommendation had it spot on when they suggested that you keep cartridge cost at about 5- 10% of your total front end's cost..until you're hovering around Manticore Mantra, Heybrook, 'Upper' Thorens, 'Upper' Ariston, Linn Sondek , Roksan territory...
This general guideline in building an Analogue front end you can enjoy for years without major upgrades was of course was based on *as New* prices
It's a different market now that second hand turntables can be so easily sourced, but the principle still holds water if you simply factor in the quality of a turntables moving parts (main bearing, tonearm pivot bearing, isolation , suspension , motor , drive system etc ) against the quality of the cartridge you're hoping to hear at its best...(and hopefully un-compromised by any lapses in quality in the turntable itself.)
I am still inclined to think, after many years of tinkering with turntables, that venturing much above a budget benchmark like the AT-95E, AT-110E, Ortofon OM-10 , OM-20 , Goldring 1012 or any modern equivalent in terms of performance, really requires a tonearm of *at least* the same quality as a Linn Akito, Linn Basik , Rega RB250/300 or Jelco equivalent to enable the cartridge's sonic potential to be assessed fairly honestly.
This probably applies as much to budget elliptical cartridges as it does to the more expensive mm or mc transducers but..as always experimentation and auditioning using your own ears is often the best way to decide which route suits you...and your wallet :thmbsp:
