Ten Percent Distortion?

I have a little Panasonic SA-XR25 digital receiver for my TV rig (I can't really call it HT). Driving some good speakers it sounds great, and cost me all of $287. Tonight I was killing some time wandering around the Best Buy shop looking at similar electronics from Panasonic, and others, and I noticed that output power was quoted at 10 percent distortion! At first I thought this was a missprint, surely they meant 1 percent or even 0.1 percent. However several units, from several manufacturers, were described this way. Back home I quickly checked the SA-XR25 spec and was reassured to find a reasonable 0.3 percent stated.

What the heck is going on? Wouldn't 100 watts at 0.3 percent sell better than 140 watts at 10 percent?

Actually, the 100wpc at .3% distortion amp sounds the same as the 140wpc at 10%, since it is the same amp.! But which spec is more attractive? The 140wpc one, of course, so it is the one used. The % distortion is rarely quoted in big letters.

Of course true audiophiles aren't interested in the distortion figure! It is probably that 10% distortion that makes that amplifier sound better to that audiophile's ears, who naturally says that the sound of an amplifier is all that counts. That goes for power also. In fact, the lower power amps probably sound better due to the distortion!
Meanwhile, the non-audiophile, is oblivious to the "sounds better" issue and only sees watts and that is what he buys and that is the market which those products are aimed at.
