The Funk LAP-2.V3 Preamplifier On the Bench

At 1 kHz and 2 volts RMS output the THD+N I measured was a very respectable 0.00038%. Funk measures lower distortion using an Audio Precision at the factory. My test set up is very capable. It has a native distortion floor of about 0.0003%, so the distortion I measured of the LAP-2.V3 was at or near the limits of detection for my test setup.

In this test, the input signals are simultaneous 19 kHz and 20 kHz sine waves at 1:1. The B-A peak at 1 kHz is 123 dB below the test signal. This is a superlative test result.

The LAP-2.V3's Intermodulation Distortion was only 0.0023 %.

The measured frequency response of the Funk LAP-2.V3 is essentially flat between 10 Hz - 96 kHz (the limits of my test gear). Notice that the major divisions of the vertical axis are only 0.5 dB.
