hey I own a pair of alon II mki powered by my audioprism debut tube amp 50 watts x2 and it sounds really wonderfull with plenty power to spare never go past 10' on the volume knob,speaker placement is the key(done it so many times!:)).
should work with the golden amp but not sure about their power efficiency all amp are not made equal,the original golden did not seem to have a solid reputation,mk2 might be better.
if you have a chance test it first that would be the only way to know for sure.
soon will be running the alon with a second A.P amp on repair for know.
the added power does bring out more bass out of the sealed enclosure of the alon,but if your amp has good high current power,the 50 watts will do the job but more might be better again mostly for the bass.good luck Thierry.
