The Red Sparrow I had on my Kuzma for a two week demo. Fantastic cart. I can't unhear it now. Interesting though, I didn't find it to be fussy. I did find it very sensitive to VTA. But once you nail VTA, which wasn't difficult to do, boy does it sound wonderful. Soundstage depth like you've never heard. Ever. Detail and dynamism and yet never fatiguing. I did think it was maybe a touch lacking in the bottom end. Certainly not "thin and sterile" though. Not even close.Red Sparrow: It is a very fussy cart so be warned. If it works, it is incredible as though no cart is there. If it doesn’t it will sound super thin and sterile.
One downside: it was a very low rider. So low in fact that I couldn't use the Kuzma periphery ring because the Red Sparrow body would contact it.
