..there really is never and end. Instead of asking strangers/friends, go to live musical events of performances you really like, and understand what real music sounds like. After awhile, you will know what to alter in your system to sound like the real stuff.
What should I add next?
I finally got my techniques 1210 up and running and I must say I am very happy with the sound quality. I was just wondering if it makes more sense to invest in some of the Kab Mods(fluid damper/Tone arm rewire), or invest in a better preamp(I currently own the low end MM cambridge which does not sound any better than plugging my player directly into my receiver--13 year old Kenwood), cartridge(low end Grado currently), or speakers(looking to spend around 500$ for a pair). I also have the Sumiko headshell, but have not gotten around to using it,and an Isoplatmat. Any suggestions would be great--Cheers
