It would appear these are the same amplifiers with a few cosmetic differences and possibly a front mounted power switch on the Emotiva, where as the Jamo's power switch is located on the rear. Similar layouts and same specs would indicate they are made by the same manufacturer. If you look at detailed pictures of each you will notice all the screws are in the same places, note the Jamo sinks there screws for cosmetics.
Here is a link the the Jamo-

The Jamo may have better WAF, but is it worth more than double the price?
Just thought I would share this interesting find, not that it is terribly relevant. Or it may save someone some cash.
