The Pico dac is excellent, especially considering price and size. I've used it in my home system when my Duet was out on loan with a Cary SLI-80 (speakers and headphones) and while there might have been some drop off in SQ, I could have been very happy with the SQ I was getting. I can't say how it would be with your G'lite or which amp is better. Buy one, try it out and if it's not what you want, return or sell it. Let you own ears decide, if at all possible.
