Very good value for money. Sound reached the level of 5.1 amp system with HP Yamaha and Sony. We feel a clear difference to go from 2.5 mm2 to 4 mm2, then buy without hesitation, you will not have to regret it! And for the price, it is more than a good deal. I did not find cheaper on many websites and in stores. Certainly this is not high-end but for home use, it is already very good. So why pay more and do not necessarily feel the difference.
