I thank all of you for your input.
I am not as technically astute regarding hifi as some of you must be. I have been using Robert Harley's "The Complete Guide To High-End Audio" fifth edition, to determine the actual power rating of amps. According to the table and calculations in chapter five, pages 86-87, the Belles amp I am considering is rated at 125 w @ 8 ohms. and the same watts @ 4 ohms although it is given a 225 w rating @ 4 ohms by the manufacturer. Does that sound right?
