What could help is if you got ahold of any reviews or auditions of Proton's AA-1150 or D1200. I don't know the relationship between Proton and Onix but I'm sure Proton manufactures this amp for Onix. It is the same amp as the Proton D1200 but 20 wts more /channel and no DPD (Dynamic Power on Demand). They both are identical in look and weight. I own the AA-1150 (50 wts /c) and D1200 and they are very bright sounding! No doubt about it! If the A-120 holds true to the original design it is probably as bright sounding.
