The Citypulse DA7.2x DAC, which upsamples to 96 and 192 kHz, can be used as a standalone DAC or headphone amp or single-source preamp if you're only playing digits, with fixed and variable outputs and volume control. (This is a stock unit and doesn't have the TCXO upgrade.)
I found that the addition of the tubed MF X-10/V3 made a really good DAC sound outstanding. I have one for sale and highly recommend adding the MF to the DAC. Send PM for package price.
Comes with a nice Philips universal learning remote, which you can program eight devices into. The Citypulse didn't come with a remote, so I'm adding this to the package. You'll have to dig up the code for the Citypulse, since I used it as a DAC only.
