You mentioned in your original post that the amp will be used to power the "top portion of my wedgies". So, if I understand it correctly you will be bi-amping your speakers (sorry don't know what wedgies are). If so, how are you setting the levels between the two different amps? If you could do it with two separate and different power amps, you could certainly do it with one of the two amps being an integrated, by running it fully open and treating it as a power amp, albeit one with perhaps a bit higher sensitivity.
Since you were looking to buy the Ampino, here's what the designer of the Spark (who is also the distributor of the Ampino) had to say about both:
"Ampino has higher power and benefits that come with it. Also, Ampino's sound is not typical for solid-state units - it adds just the right amount of warmth and character that make it very easy on the ears.
Spark, on the other hand, stands out with how it resolves the upper part of the spectrum - that is, IMHO, what puts it above other amplifiers in its price range. That characteristic is the first thing I noticed on the very first prototype, and I am happy that it only got better as we worked to finalize design."
From this description and given your stated application of powering speakers from the midrange and up, I would think the Spark to be the better suited amp between the two.
