Here's a single 35lb Emotiva XPA-1L "Gen 1" monoblock which I bought back in 2013, a few months after it was released. Far from the most expensive monoblock amplifier out there, costing a "mere" MSRP US$699 each:
Over the years, I have seen a couple of (p)reviews from Audioholics and The Poor Audiophile, but have not seen any independent measurements of the output quality.
From late 2014 until they discontinued this model (not sure when), Emotiva also made the "Gen 2" model which cosmetically looked slightly different with black instead of silver side trims. I believe internally they also made some changes which were more about cost-cutting than affecting the sound quality.
