The Shelter 9000 is everything the 7000 is and much more. The new flagship cartridge has the most sophisticated generator system of any Shelter cartridge ever designed. The old Shelter 90x was a killer cartridge, but the new 9000 is exceptional! Every 9000 goes through many hours of tweaking and listening, and more tweaking, to ensure you hear every single bit of information buried in the grooves of your LPs. This cartridge has the highest tolerances of any Shelter. Whether you listen to Classical, Rock or Jazz (or all of the above), this cartridge get the tonal quality of any piece of music right. You can’t go wrong with the new Shelter 9000.
