I already commented to scaling, both here and in the review.
Utopia scales down poorly; it needs lots of power to overcome the impedance spike. Also, since it's so clean when driven well, the looseness from the poorly driven bass is more jarring. Scaling up, I suspect we'll be seeing Utopias at a lot of amp manufacturer tables since it's really good for showing off what your amp is capable of.
Elear scales down better than the Utopia. Its impedance spike is smaller, for one thing. And for another, since the bass is a little bloomy already, loosing some of the control doesn't seem nearly as jarring as it does on the Utopia. The Elear sounds good on good equipment, but it's simply not as technically proficient as the Utopia and isn't going to show off the resolution of high end equipment as well. That means it scales up to a point but beyond that it doesn't really need a crazy good amp.
This is all in my humble opinion and based off the limited time I had with them for the review. Once I get to spend more time with them, my opinion may change. YMMV
