Introduction

Ever wished you could own a truly high end esoteric digital player but your budget is limited to mass market players? Joe Rasmussen from Custom Analogue Audio reckons he has the answer. Using a cheap mass market universal player (the Marantz DV6500, normally retails for A$799 – US$649), Joe has upgraded it with technology from Vacuum State Electronics (Joe is the Australian agent) to create a “state of the art” two-channel universal player called the “JLTi SACD Player” that is being sold by Pymble Hi-Fi in Sydney, Australia, for $2,500 (~US$1,900).
