I would also consider the arm/cartridge pairing as you go down this path. Ask someone like DougDeacon about ZYX cartridges. He seems to have a lot of experience.
PASS and ZYX
Has anyone used the PASS XP-15 with the ZYX 4D-S MC cartridge? I currently have the Glider high output and the Audio Research PH3SE. There is barely enough gain without the PH3 yet using it tends to overdrive the phono section. Hence, the desire to change both components and add some flexibility. There seems to be a lot of good buzz about both components. Thanks in advance.
