Hi there I am glad to say that I am a proud owner of the Yamaha AX500/u Amplifier. Mine has been in storage nearly all of its life as it was hardly used by my friend so I bought it 6 months ago. And it really looks like it just came from the shop. Probably best condition one I ever seen. Well to get straight to the point. The Yamaha AX 500 is an amplifier that is made for Extreme Clarity and loudness for music; I would not recommend this amplifier for watching films everyday as i say it would be a waste of Amplifier , Although it may still sound clear this amp does not have the features to make your home cinema effect. But I will guarantee that once you heard this mean machine it will be music to your ears in the sweetest way. Features: ALA (Absolute Linear Amplification) is circuitry that gives high end sound and gives you a distortion free signal to your speakers. This will handle high ranges of digital sources of music. High Dynamic power & Low impedance Drive, is designed to make your amplifier handle the extreme power smoothly, virtually with any speaker load with no strain However In the technical side of things, Yamaha AX 500 Specifications
85w per channel @ 8 Ohms x4 as is a Quad Amplifier so total power on 4 speakers is 340w & 8Ohms all in. Hands down I had a pioneer 500w amplifier and my Yamaha AX 500 really made my pioneer sound like a cheap pathetic portable cd player that was as useful as a chocolate fireguard. So what I am saying is the Yamaha AX 500 has much more than what meets the eye well and truly. Overall rating is 10/10 for people in love with high quality music especially loud and clear.
Good review but could do with some more info to gain higher ratings. Take a look at other reviews to get an idea of the level of info that is needed to gain higher ratings. ~ Em. x
