We love amps. Adore them. And we have a special spot for DACs and DAPs (pocket audio players, to non-audiophiles) too. So we spend a lot of time messing around with them, considering them, trying them in a variety of wondrous combinations. And whether we're losing ourselves in tubey valve goodness or knuckling down to a solid-state fistfight; whether we're tweaking the parameters of our DAC or uploading songs to a DAP, we're always observing. And here, we've condensed those observations into the best damn collection of reviews anywhere. Enjoy.
