Very beneficial. Cannot be overstated. Progression from old Target stands to Quadraspire SVT to Quadraspire Reference X has not only solidified my belief in their value, but also their value for each component stationed on top.
I've no TT, so step back from that. I will confirm that each component benefitted.
My wife's system (Rega Apollo R CD, Mojo Mystique' 3 DAC, Luxman 509X integrated) initially set up on an IKEA bench. Sounded really good. Then planted everything on a Quadspire SVT stand. Remarkable improvement. Dynamics, attack, separation of voices and instruments, blacker sound stage, all improved dramatically. It becomes a question of how much improvement, not if.
BTW, ATC SCM 20 monitors are on Sound Anchor stands with Herbies Fat Dots. Again, a real improvement from Sound Organization massed with sand/shot.
Enjoy your journey to audio Nirvana.
