I had a 20 amp UO for a few years and then bought a Quintet. I believe it is better as it is newer. PS Audio claims to have made improvements. But I use it only on a few components and it is plugged into a Running Springs Jaco. So as far as sonics I can't give a fair evaluation.
But I like the size and the switching capabilities, which the UO didn't offer.
