All of Schiit Audio's headphone amps can be used as a preamp. I own a Modi Multibit (DAC)/Vali(tube headphone amp/preamp) combo that I am using in my bedroom. It sounds fantastic.
In my main system I am using a Schiit Jotunheim with a phono card. It gives me one phono input, one RCA input and one XLR input. It has XLR and RCA outputs. You could substitute a DAC card. I went external with a Gungnir Multibit. If you want a DAC that is the same size that would stack with the Jotunheim you would be looking at the Modius or Bifrost DACs
My living room system...the system I have had the longest...has a Saga and Modi3. I really like all of them. I also admit to being a Schiit fanboy that prefers tube amps.
On the low end you could have a Modi 3/Magni combo for $200, a Modi 3/ Vali for $250 or a Magnius/Modius for $400. The Jotunheim is the only headphone amp/preamp that has three inputs. The $100 DAC card is a USB only Modi. The $200 Multibit DAC card is a USB only Modi Multibit.
