Turntable sounds so much better when...

and maybe VTA/SRA.

Thank-you R. I have had this Turntable for years it's 1978 model..Never did i hear it Better untill 2 days ago...I am just delighted at the improvement..including absoulty No Sibblince in songs that was very present.i.e.Peter Gabriel "So" Richard

All you guys have been incredibly helpfull to me with understanding the reasoning why...And to think i was unsure of posting for fear of being rejected i guess. Thanks All.. Please at least try this if you have a removable headshell..and let us know..Richard

Sounds like when you loosen the head arm connection you are cutting it off from a direct connection of the negative, stifling, resonance that takes place in the arm itself.  The cartridge sends micro vibrations down the arm and that arm when locked tight fights how the cartridge wants to vibrate. The principle is like the old Victrolas that used to amplify the needle vibrations  into a big horn.  So.. You are decoupling the arm (to a degree) that has resonances that fight the cartridge from flowing optimally.

Sounds similar to the "not too tight" motto for the tonearm armboard nut on the Rega RB300/250, if over tightened the sound became deadened. Another thing might be the MC cartridge sending vibration back down the tonearm (I think more than an MM cart?)
