PS Audio Sprout100
The all new Sprout100 is a power house integrated amp in a small form factor. This new Integrated Amp has everything you would expect for today's world with a high quality DAC, Phono input, analog inputs, 100 watts per channel power and if that is not enough a sub-woofer output for all of you bass hounds out there. PS Audio doubled the power in this new version of the Sprout so you have a lot more flexibility in speaker choice with this model from the previous model.
