Are you going to keep the revels long term;if so I would concentrate more on proper matching of the amp to the speakers rather than the amps make .
To me it seems that the impedance drop to 2.5 ohms may make the 30 watt amp a little short of power;but I don't know the frequency of that drop.
The only way to really know if to audition the amp(s) in your enviroment.
