Other Notes: The 540P features a moving magnet stage whilst the 640P offers moving magnet and moving coil stages. Both use discrete transistors for the all-important input stages instead of the more common integrated circuits.

Both are designed to produce high gain and linearity, without requiring massive amounts of negative feedback to achieve low distortion. These new models also employ a single-ended ‘Class A’ gain stage with audiophile passive RIAA equalisation.

High quality components are used throughout such as 1% metal film resistors and close tolerance polypropylene capacitors.

The 640P uses more exotic amplification circuitry to provide even lower distortion and noise plus the higher gain stage for MC cartridges. In addition, the 640P employs multi-parallel capacitors to achieve exceptional RIAA accuracy of only 0.3dB up to 50kHz and features a defeatable subsonic filter.
