This amp is fine if you have medium-to-high efficiency 8 Ohm speakers. But it cannot drive low impedance speakers - too feeble power supply cuts peak output at about 40 wpc/4Ohm. See my other comments in Reviews here.
Follow Ups:
At sine signal and 4Ohm-0.5mH load equivalent, both channels in phase, output clips at about 18-21V peak (depending on AC line fluctuations 210-240V) - that's 40-50 WPC. Internal power rails are 37-42V at no load, at max unclipped load they are pulsing in 25-32V margin. Time to beef up caps. 4700 uF per channel per rail is too low.PS. The manual (European market) says nothing about 4Ohm power.
PPS. Did anyone try to fill the empty capacitor slots on the PCB? I guess these are for input-driver stage only.
...the Audio Refinement Complete does 90 watts into 4 ohms.Sean H
I power Reynaud Twin MK 2's, which are 90dB/4 ohm with amazing ease. Taste. Room. Many factors to figure in before concluding your assessment.Sean H
Did you even read the man's associated equipment?Karlotta
