There are only 8 ohms in both modes and bridged. But have you measured it on 4 ohms too?

Yes, and the output power into 4 ohms is discussed in the measurements text.

Shame that it's massive near 40kg weight doesn't reflect in it's current ability into low impedances like normal true complimentary NPN/PNP push pull bi-polar amps can. EG:JC1's, Agostino, Krell ect etc

A little lame in it's current ability into the low impedances of the Alexia, hence the "bass was a mite wooly" sound description by Jason into the Alexia's, even though it has nice low output impedance .012ohm?

Cheers George

Seems like a lot of juice and hassle for an amp that is just very good
