I'm so far a bit on the fence about my Pontus 2 as well. I do hear the "thin" that you're talking about. It has very good texture/timbre of instruments, good space between the instruments. But it sounds thinner than my Bel Canto. Although more lively at the same time, it's hard to explain. the Bel Canto is just a bit more dark/relaxed than I thought it was, until I did a comparison. to compensate, I would turn up the treble energy on my Tannoy Arden speakers, and it sounded very nice that way! With the Denafrips, I had to turn the treble energy down. It just has a different type of "flow" than the Bel Canto. Only a few hours on it so far though so I dunno whether to draw any conclusions or not yet.
MHDT was also on my list, along with Audio Mirror Tubadour III SE. Maybe I will have to try one of those at some point.
Trying to decide how much time to give the Denafrips. Leaning towards giving it awhile because I am the 2nd owner, warranty won't transfer again, so I'll probably lose a fair bit if/when I sell it.
Great build quality on it though! And I don't think it sounds bad by any means, just much different than what I'm used to. The Bel Canto does sound "fuller" somehow. With the trade-off of losing some of that "edge"/realism of the timbre of instruments.
