The Red is the entry point in Ortofon's new mid-price Rondo MC line. Rather than plastic or metal the Rondo bodies consist of ground Japanese wood in a resin matrix. The theory being this wood/resin concoction is ideally suited for minimizing unwanted resonance effects, which is critical for cartridges. As with anything else, spending more will generally get you more, in this case styli. The Rondo Red features a Nude Elliptical with aluminum cantilever, the middle child Blue ($699) has a Nude Fritz Geiger 70 and the top Rondo Bronze ($849) sports a Fritz Geiger 80 and tapered aluminum cantilever. Otherwise the specs are identical: 10.5g weight, 2-2.5g tracking force and 10-200 Ohm load impedance. I expect as one moves up the range the basic character will be identical but with greater detail, nuance and refinement.
