Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
Well cared for and lightly used (if at all) cartridge from Ortfon. Under the microscope I could not identify any signs of use or wear. A great value.

The SPU Synergy G modernizes the classic SPU design with a number of optimizations designed for optimum compatibility and sonic purity SPU Synergy G.

The SPU Synergy features a wood-based housing and has a revised generator system which allows for a maximum output of 0.5 mV, relaxing the requirement for high gain transformer or active preamplification systems.

For optimum compatibility and sonic purity.

Features
The SPU Synergy features a wood-based housing and has a revised generator system which allows for a maximum output of 0.5 mV, relaxing the requirement for high gain transformer or active preamplification systems.

While still making use of a highly polished Nude Elliptical stylus, the stylus tip mass has been reduced significantly, resulting in reduced VTF and higher tracking ability.

Testing Process:

We start by doing a detailed physical inspection under light magnification to asses the cantilever condition, its position in the cartridge body and the condition of the suspension. We also inspect any coil wires and the output connections to make sure it hasn’t been strained. We then perform a light cleaning with specialized agents and blow it dry with compressed air.

We then perform a more detailed inspection with our Wild Heerbrugg professional microscope. From there we can asses the wear and quality of the stylus and determine how much use it has had and if there are any mechanical issues. We can also identify if it needs further cleaning or care.

We then move the cartridge to a digital microscope where we take photo os the cantilever for future reference.

We then move to the test bench where we can check for continuity of each channel and resistance.

On certain cartridges and it the technician feels necessary we install the unit on a turntable and run a few test records to ascertain tacking ability, distortion and compliance.
