The value for money is still good, but the musicality of this amp is really average and I do not agree to call it a HI-FI. I bought this to get an idea of the interest of the class T. Due to its operating principle, and despite its armor, there is radiation in a broad frequency spectrum close to the unit and within a radius of about 1 meter minimum all around, for example prohibiting receive amplitude modulation radio stations in the band of PO if the receiver is nearby. It is true that today all electrical appliances radiate and give heart-joy, we are immersed in the electro-magnetic radiation. This remark is only useful if we consider that it is better to avoid when we add the choice.
