NuForce HA-200 Headphone Amplifier
Other HA-200 Features
• A single output gain stage (only 1 op-amp and 1 output device in the signal path)
• A high performance Alps volume control
• XLR connectors for operating in “Balanced Headphone Mode” (see above)
• A linear power supply comprised of a custom-made toroidal transformer and extensive capacitor reserves
To be sure, the HA-200 is not a headphone amplifier for the common man or woman. Developed specifically for
the devout headphone enthusiast, it’s comprehensive design and pristine audio performance is reserved for
those that demand nothing less than the very best.
In the ‘Balanced Headphone Mode’, simply use the XLR input (one on each HA-200) and output.
