Audio-GD R-28, if you want a R-2R resistor ladder DAC instead of a 9038 chip, but essentially the same thing.  $1159 USD for fully upgraded version.

These are top tier DAC/preamps, but you will need an external streamer if you want to stream.

I had the earlier 3.0 version of this Bel Canto DAC in my system on extended demo and it is excellent, especially with the separate VBS power supply. You can read the reviews. I also used it as a preamp and it was indistinguishable from my Bryston BP6 stereo preamp, which I thought was pretty amazing. No streaming, but I think it does everything else you’re looking for.  Original list price of $5440, so at $2300 I think it's a great deal too.  Best of luck.

Oppo HA-1. has one pair of XLR and one pair of single end RCA input for pre-amp. It is a class-A preamp and earphine amp. mainly it is a DAC based on ESS9018 which is very good DAC for DSD and Hi_res music.

Thank ahofer, that cambridge looks awfully nice. Seems to fill all the requirements except price, still a little pricey at least up here north of the boarder. Lol. 

Nuprime DAC-10. Meets all your requirements but no balanced inputs.  I have no connection with the seller but there is one for sale on AudioCircle for a good price.  

I have this. It does what you want. Sounds great.  They went a different direction from the past with the DAC.  The streaming features work really well also.
