Again, I'm only speculating on shared components/manufacturer between the Dayton and this Emotiva. This assumption is not a stretch by any means, since the precursor to the Emotiva Mini-X A-100 was the BPA-1, which is a clone of the Dayton AP150 (with a different front panel and volume knob).
Emotiva was an OEM supplier long before they sold internet direct, so there are lots of audio components floating around that differ only cosmetically from the equivalent Emotiva product, all made in the same Chinese factory. Tonewinner is the name of the Chinese company that manufactures all of Emotiva's stuff now, although it may have been someone else that made the Dayton APA150/Emo BPA-1.
Customers are initially drawn to Emotiva for their high value, so when another product beats them on value, it's noteworthy. Especially when it's very likely that said product was designed by Emotiva engineers anyway (as is likely the case with the Dayton APA150).
If space is really a premium and you HAVE to have the glowy blue bits, then this Emotiva is the product for you. If you want the same amp with more features (bridgeable and built-in lowpass filter) for about 40% less $, then get the Dayton.
