Thanks, jaywillin! It's definite that the Mad Ear+ has a proven track record (and absolute synergy with Grados), but the Lyr2 is the newest kid on the block with the latest and greatest (and at half the price).
I'm sorry to hear about your misfortune. You said that you're looking for a DAC and an amp, and this version of the Pico is only a DAC. Listening straight from it means you'll only be able to hear your source at full volume.
