O2 vs. Magni (better experiment with output taken from HE-500)

Similar two tone test. 100Hz and 1kHz. The actual SPL is about +3db louder than reflected in the graphs. 16K FFT (will use higher rez in later measures)


(It says ODAC, but it really is O2 in the graph below)

Darn! Any differences if you drive the HE-500 with the tremble multi-tone tests but louder?

Lower level two tone. Don't know why I typed in ODAC again.

Shut! My reasoning was that the Magni could probably go louder and/or handle more dynamic range (in the time domain, which means many tones) before crapping out, relative to the O2, but so far nuttin!

The O2 was already maxed at its current gain setting. I think the distortion we are seeing is more from the driver than the amp.
