I bought this amp for both the home theater for music listening in a new room dedicated 30sqm. I coupled with Jamo speakers HCS 102 (5.1 satellites) with cable 1.5mm² (between 5 and 10m cable per speaker). The sound is of a purity that I had rarely heard, even from vendors with facilities of other brands and much more expensive. At first I told myself that this amp lacked power, but in fact it is the quality of sound that gives this impression. The amp is powerful enough sound to my room. In any case, although it is not noticed the power which was favored by Yamaha for this model, it is the quality and purity of sound. I listened to the albums I used to put in my car and in my living room (+/- 20 Pioneer system) (eg Pink Floyd Division Bell) and there are details I n ''d ever heard. At too low, rendering is also of very high quality. With the extra bass function, low frequencies are distilled with precision and subtlety that I did not know. This is not the big sound nag unbalanced one sometimes hears in some 'cars' or some bars, it is very subtle and powerful at the same time (I had never heard so distinctly on the double bass drum Mouth Pantera of War for example, or the bass lines of the Red Hot or Shaka Ponk). The various DSP modes are nice, although I do not really use. The stereo to 5.1 conversion is top notch, the sound is very well balanced. Regarding cinema, frankly it's a flawless, the sound is crystalline, slap and video signals (blue ray 3D Xbox ...) are handled flawlessly. Before buying this amp on Amazon, I did some specialized vendors (audiophiles) and I must say that this amp amps much competition, but then much more expensive. In addition the installation is super easy and Titanium color is really beautiful. I wanted black at first, but saw the discount Amazon offered on this color, I made this version and I do not regret at all (it is much more convincing in person than in the photo). This amp is super class. The price offered by Amazon, it's downright unbeatable.
