Audiophiles simply love vacuum tubes, devices that give audio a warm, analog sound. The problem is, they’re insanely expensive, meaning they’re usually only available to the craziest and most well-heeled of enthusiasts. But this MiniWatt is a vacuum tube amp that you can actually afford.

For a relatively reasonable $229, the MiniWatt is a diminutive little amp, but that doesn’t mean it doesn’t pack a punch. The geeks at ToneAudio magazine hooked it up to a pair of $3,500 speakers and it blew them away. If you’re looking for a cheap and easy way to give your setup a big boost, this could be right up your alley.
