    Good amplifier, clear sound. High efficiency. Use this with a 19 volt laptop supply with max current of 3.5 ampere and output power of two times 25 watt is easily possible thanks to the high efficiency. Remarkable low radio interference on medium wave and other AM frequencies! Stays cold/cool with higher output. Good choice also for Li-Ion (4 cells in series) and portable use. Frequency range 19 Hz to 25 kHz zero dB when loaded with resistor. Some deviation of frequency response with complex load,

    Working great so far. Got it connected to an old pair of tv speakers and a 12v power supply. Bluetooth paired with my (linux) laptop, I'm happy :) Aux in works as well (turns off bluetooth). Aux out also works, but low volume, need to experiment some more. Have not tried the usb connection yet. The soldered connector "legs" stick out from below, even with the base plate attached, though the screw heads give some extra clearance. I think I'll add some rubber feet, just in case (and make it less slippery

    Comme il fait nuit, je ne vais pas vous infliger de mauvaise photo du produit; vous devrez me croire sur paroles: 1- le kit est arrivé...en moins d'une semaine (il fut expédié de France, à la différence du reste de la commande) 2- l'emballage est moyen-moyen (sac extérieur discret, passe-partout, intérieur sachet pour pièces, et sac bulle pour la carte) 3- l'assemblage prend 10 minutes, un peu plus si on est pas prêt, ou si l'on veut observer l'assemblage & les finitions; pas mal 4-

    It is a good way to make Your self a Bluetooth speaker system Easy to setup and works out of box without big hassle. Sound is little flat, but power is aceptable. Using 19V laptop powersupply it made large speakers to rock. For this price it is very good gadget. Recomende (Y)

    Awesome product, easily powers two HI-FI speakers, with interference of buzz in background. Multiple input options. Power supply is missing, however for 7.99 it is no problem.
