Had the Pi2AES for a week and I'm very impressed with it. Compared to the digione, the Pi2AES has a bit of inherent warmth that is very pleasant without any loss of detail. I was hearing a bit of harshness in the upper mids of the Soekris DAC2541 that I was attributing to the dac, but I could no longer hear this with the Pi2AES. You also don't have to worry about expensive linear PSUs and battery packs, which is a huge bonus. I ended up ordering two of these. One for myself and one for my dad. Great stuff! It really is a game changer having a digital source without any of the nastiness that comes with digital for such an affordable price. Add the convenience of controlling the streamer from any device.
