FWIW, I once had a Spacedeck/Space Arm. Tried my Grado Master (HO) on it and never could get the sound to sing. Not bad sounding, but didn't sing like it did on my Well Tempered Super. A Dynavector was great on the Spacedeck, but didn't work as well on the Well Tempered. Synergy does matter, regardless of the cost of the cart.
Low and high output Grados differences in detail.
Do the high output Grados have more detail then the low output Grados. I have a Aesthetix Rhea Phono Amp and was wondering if Grado carts would be to "mushy" with the Aesthetix Rhea? All opinions and expert advise is welcome.
