In my opinion I think before thinking about an upgrade, always look at the bigger picture. When it comes to records, I would look at:
1) what am i actually playing, Ex condition records or used records, Bollywood records or western music records, Genre of music, indian pressing or other pressings, 180g vinyl, thinner pressings or picture discs and similar considerations
2) what kind of chain do i have, is the chain capable of reproducing change resulting from the upgrade
3) what are the demerits of the upgrade (often overlooked) - there can be many, when i change from my humble M44-7 to my marquee V-type III, many of my older records wont just play the same, some Indian pressings sound like they are being played through a speaker placed in an earthen pot
4) am i a person for originals/stock condition or am i a person for customized hot/rods
5) will i be able to revert to the original specs without much 'damage'
6) do i actually need the upgrade - cost/benefit analysis - do i need to pay all that more for just that decimal percentile of betterment, is it worth it for me?
7) will this upgrade be relevant only if other upgrades are also initiated - will this one trigger off another set of upgrades
8) am i looking purely for listening pleasure or bragging rights or both - am i doing this for myself or to impress others or both
9) am i looking at potential investment options - yes there are many who invest in audio equipment as an investment option
10) maintenance costs for the new upgrade
