My upgrades and what I perceived to be an audible effect for my TT rig (VPI Jr., JMW 10.5, Benx Micro Glider, Innersound Phono Stage - purchased TT with Bright Star Big Rock so neverplayed w/o it).
1. Added Living voice TT mat & BDR record clamp and felt all was a little quieter and smoother sound. Dynamics increased a bit.
2. Added SDS and noise floor went way, way down; better detail, soundstage, dynamics & better bass impact; more air around notes, wider & deeper soundstage - obviously needed speed stabilized & corrected.
3. Upgraded outboard motor; upgraded power cables on SDS & motor to Shunyata Hydra Diamond back as well as shunyata taipan to preamp and phono stage and felt the front to back was deeper and the notes had a little more room. I didn't realize I had motor noise until I upgraded to the new motor. Background became very black; music just came out of the soundstage. .
4. Upgraded TT IC from stock Monstor Cable to Cardas Phono IC and didn't really experience much of a difference. (felt better doing it, though)
5. Upgraded power conditioner from Richard Gray 1200S to Hydra 8 and brought system to another level-the air around the notes went up multiples; absolutely no noise and incredible black back ground. Music just flowed from a black, wider and deeper soundstage.
6. Added Shakti Holographs - more demensional, wider sound stage. Better detail and transparency and I thought it was pretty good before I aded them.
Just my 2 cents~
