Looking for a new Amp or Preamp? If you're after tubes, post over here.

Reading comprehension problems, A.Wayne?

" The M1.1's discrete clipping powers (at 1% THD+N) were 140W into 8 ohms (21.5dBW) (115V line); 138W into 4 ohms (18.4dBW) (114V line); and 230W into 2 ohms (17.6dBW) (115V line). "

The Lamm puts out 230 watts into 2 ohms at 1% and around 400 into 1 ohm.

That is in the low impedance mode.

The M1.2 was more thoroughly tested in the high impedance mode and records the following:

" Fig.4 shows how the THD+noise percentage present in the M1.2's output varies with output power with the Hi-Z bias setting into loads varying from 2 to 16 ohms. The amplifier comfortably exceeds its rated output power, giving out 180W into 8 ohms (22.6dBW), 305W into 4 ohms (21.8dBW), and 490W into 2 ohms (20.9dBW), all at 1% THD. "

So, in the high Z setting it makes nearly 500 watts into 2 ohms and half that at the low Z mode (so about the same as the M1.1) and doubles again into 1 ohm.

That is a LOT more power than you are claiming. Not 5%, not 3% but 1% THD.

"The M1.2 Reference is conservatively rated to deliver 110 Watts into 8 and 4 Ohms in pure class A operation (high and low impedance settings, respectively); 220 Watts into 2 Ohms, and 400 Watts into 1 Ohm (low impedance setting), continuous."

Since LAMMs specs were accurate at 4 and 2 ohms, I don't doubt that they are correct about their 1 ohm output (in lowZ mode). One may also safely assume that LAMM rates these at 1% THD...just like Stereophile confirms.

So, your numbers are simply out to lunch.
