What Hi-Fi? Sound and Vision Five Stars
" A clear class leader. It sounds strikingly clear " , " We get a fast, rhythmically taut sound that' s as exciting as it is informative " , " The sound is agile enough to resolve a complex mix like Eminem' s Not Afraid, while having the sophistication to make Beethoven' s Moonlight Sonata sound like the slice of magic it is " .

" Where the Yamaha moves ahead is in sound quality " , " The talented A-S500 is without doubt one of the major surprises of our year " .
Yamaha A-S500 has a semi- dual- mono construction; the two channels using separate transistors ( two for each) , “ mirror” construction until separate filtration, having in common only the transformer, a very rare construction in this price area. Yamaha A-S500 has a more than sufficient power for a home Hi-Fi system. It has an absolutely decent number of inputs and the amplifier also supports two pairs of speakers simultaneously coupled. Its construction is very solid; A-S500 gives the impression of an expensive device because of the metal front side and its dimensions, being built on the same pattern with more expensive models. The variable “ loudness” can prove to be useful for low volume and there is also a Pure Direct buttons, which completely eliminates the correction circuit.
The remote control is quite an important utem for many of us. First of all, the remote control offers a pleasant feeling, using a combination of soft plastic and aluminum very well integrated.
