I was talking to Tuberoller a couple of days ago and he mentioned these to me. I've never heard of this line from Parasound before but he said they sounded pretty good to him. Audio Advisor is selling this line of components and what struck me in their latest catalog were the words "independent headphone amp" when describing the features of the Halo P3 preamp. There was nothing else mentioned about the headphone section, though. This might be something worth trying out in a dealer showroom. I think the series looks very nice, too. Go here for more info.
