Nice little amp, seems well made from the outside. i forgot to order a power supply so im running it off an old 19v laptop PS and it seems to be running my small Philips speakers nicely, better than the original Philips unit did anyway. Stated DC input range is 24-48v so looking forwards to getting a gruntier supply and seeing how it goes. Suggest the seller provides a bundle option that includes a suitable Power supply. Reccomended
Good sound quality and deep bass.
