“Our current Zphono is the ideal product for entry-level vinyl lovers” said Richard Schram, Parasound’s president and founder. “We’ve noticed the fast-growing popularity of more expensive turntables and increasingly high-performance MM and MC cartridges. With the Zphono XRM’s adjustable load impedance knob (rather than DIP switches) MC cartridge users can easily make on-the-fly adjustments to achieve the best sound. With its rumble filter and mono-stereo switch, the Zphono XRM provides even more control to the increasingly serious vinyl lover.”
