Heddphone one amp+dac/combo. 2k USD

A few days ago I got heddphone one. It is awesome but my asus xonar essence stx ii does not have enough power to make it sound properly. So I am looking for a dac amp combo or stack. For max 2k usd. I’d love to warm the sound a little bit, without loosing details and add some bass and punch to it. It could be tube amp but not necessary. I’d love it to be balanced out as well. I was thinking about pathos aurium plus some dac. Topping a90 d90 stack. Something from schiit. Cain iha6 idac6 stack. Can u help me with some other ideas and thoughts?

I got the Cayin stack recently, and have been very pleased with it. I don’t have many bright headphones, but I think the stack is considered to be slightly warm leaning. Something like a Schiit Bifrost 2 and Liquid Platinum could really smooth it out a bit.

you could try to audition a Schiit Bifrost 2 with a Violectric V280

I haven’t had the possibilty to get my hands on the B2, yet.
The V280 is kinda a warmish and powerful enough for the HEDDphone in balanced
