Depending on your room size, distance from the speaker, and desired sound level, I wouldn’t think the Luxman would work in all but the smallest room.
This is especially true with the A3 as the smaller panels are less efficient.
Also, the panels go up in impedance with lower notes, meaning they can be up in the 30 ohm range. That would mean something like the Luxman would only be putting out 30 watts depending on the material.
For solid state you need like 300 + watts. More is better.
