DACs and amplifiers are two separate devices that do different tasks. They can be combined into one unit, but it's not something that you can just make happen. It either comes that way or not. Unless you build the entire thing from scratch (but I doubt that's an option here).
The Little Dot MK III & IV are excellent OTL tubes. So is the Schiit Valhalla. There's also the Dark Voice SE336. And the Musical Paradise MP-301 MK3.
You can use your PC as a source, a sound card for example has a DAC onboard which you can use to output to an amplifier. DACs can be good and inexpensive. You can get them anywhere from $30 to $150 pretty easily and they're more than adequate without breaking the bank. I would put more emphasis on having good high quality media over an exceptional DAC though in terms of priority of spending.
Inexpensive good DACs that are external from the PC include: Schiit Modi, JDS Labs ODAC, Fiio E10, Music Streamer II, Fiio E07k, etc.
