That was my point George, someone mentioned the Stellar M700 goes down to 2ohms, and the specs are only 2.50ohms.
It's also interesting that Stereophile didn't bother reporting specified power rating at 2ohms, but did mention THD rises into 2ohms at higher frequencies.
Like everything else, you get what you pay for and there is no free ride with Class-D amps (with reference to low impedance speakers).
We define clipping as when the percentage of THD+noise in the amplifier's output reaches 1%, and fig.5 indicates that the M700 slightly exceeds its specified power of 350W into 8 ohms (25.44dBW). Into 4 ohms (fig.6), the M700 clips at precisely the specified 700W (25.44dBW). Fig.7 plots the THD+N percentage against frequency at a level at which I could be sure I was looking at distortion rather than noise: 20V, which is equivalent to 50W into 8 ohms, 100W into 4 ohms, and 200W into 2 ohms. The THD is very low at low and middle frequencies into 8 and 4 ohms, but does rise into 2 ohms and at high frequencies.
