Hi
I just managed to borrow an Aesthetix IO Sig to see how it compares to the Whest PS.30RDT with my Universe (4D). Interesting really. The Whest is MUCH quieter and allows much more inner detail to come through. The IO is pretty noisy in comparison BUT if you don't compare the IO to anything else the noise levels aren't an issue. For me as well as the dealer the PS.30RDT was the clear winner on soundstage, speed, micro detail and musicality. The IO os nice without a doubt, a lot warmer for sure (if you like that) but lacked the sense that you were getting the most of your cartridge.
