RD, if you're going to decide on the basis of power ratings, both Yamaha and Denon(along with the other manufacturers)have to publish accurate ratings under the FTC regulations. Note however that the difference between 75 and 90 watts is only about 0.8dB(e.g. a peak sound level of 110dB compared to 110.8dB)and is hardly enough difference on which to base a buying decision. In general power doesn't need to be a major factor these days since clean power is so cheap and plentiful. Get the features that you want at a price(new or refurbished)that fits your budget.
