Dave, Gallo 3.1 speakers love amps that deliver high current into 4 ohms (their actual impedance in the bass).
I have used them successfully with Gamut D200 and McIntosh Mc402 amplifiers.
I do not believe one needs more than 200W RMS/channel into 4 ohms to play Gallo 3.1s very loud in a domestic environment.
There is something fishy about the Emotiva's power ratings. The power transformer is rated for 1200 Watts and the amplifier outputs 1000 Watts into 4 ohms???? There is no way to make a class AB amplifier output 1000 Watts continuously from a 1200 Watts transformer (not enough headroom). The over-optimistic spec is probably one of those IHF or PMPO dynamic readings that were banned in the USA 20 years ago, good for 1/10th of a second, until the fuse blows.
The DSonic amp is rated ONLY for 8 ohms loads. Most Tripath and ICE-based (class D) amps deliver less power into 4 ohms, meaning that they are current-challenged, therefore not a good match with the Gallo 3.1.
I suggest that you buy a good, honest, used high-end amp that doubles (or nearly doubles) power into 4 ohms, made by the good folks at Classé, McIntosh, BAT, Gamut, Bryston, Parasound or any other honest manufacturer that clearly states power and distortion at 8 ohms AND 4 ohms.
Unfortunately there are no great bargains in high-end, high-power amps.
A manufacturer's marketing department may try to fool the consumers, but the engineers are unable to fool mother nature, which happens to have firm laws.
One of those laws is Power = V squared/R, meaning that a 1000 W RMS power amp must be able to continuously push 63 Volts into 4 ohms speakers at low distortion, not an easy task...we are talking about dumping 15 Amps into the load, enough current to weld the speaker cables if poorly connected.
Power costs money, period.
I hope this helps
