Cartridge help
Recently replaced a worn Sumiko blue point evo3 with an Ortofon quintet blue, everything appears to be set properly but my high end is missing. The new cartridge has about 25 hours on it and is being used with a VPI Scout Aries and a Parasound Halo 2.1. Any helpful suggestions would be appreciated.
