I would love to purchase this unit, unfortunately I have no use for it right now!
Feiao, I hope I can clarify the confusion people have. In America, 90% of amplifiers/speakers advertise their max output rating, followed by RMS. RMS output is sometimes omitted on the box and very difficult to find.
I think it would help marketing if you put the MAX power output, followed by the RMS output in the specs. EX: Small desktop AMP with 50w x 2 MAX and 14w x 2 RMS.
This might clear up some confusion people have. All caused because of marketing tricks by companies that release cheap products.
