Frequency Response .................................................... 5Hz to 40kHz ±0.25dB
This is the “standard” specification with which everyone is familiar. Actually,
“frequency response” is a misnomer: technically, it should be called “amplitude
response versus frequency” for it describes how uniform the amplitude or
strength of signals of various frequencies is maintained. It is generally thought
that a difference of 1db is the least that can be perceived by ear. To better that
by a wide margin, the 350 is specified four times higher, thus far exceeding the
audible range of the human ear.

Total Harmonic Distortion
(THD+N)
........................... 0.004%, @ 1kHz into 8Ω
M easurements are made with fixed, purely resistive loads. However, since
speakers are not purely resistive, an amplifier’s distortion specifications do not
indicate what performance will be with the actual loads presented by speakers.
Perreaux distortion measurements hold for any conditions presented by any
known speaker. Further, any measurable distortion in the Perreaux is second-
order harmonics – the least offensive to the ear.
