Budget is pretty much what I can convince myself it is. The Cambridge EVOs are networks streamers integrated with a pretty decent 2.1 stereo amp (either 75watts per channel or 150w per channel). So just add speakers. But you are always paying a bit for their marketing budget.
what I think i might do is f**k around with a cheap (highish spec / low features) DAC such as the Topping D10s and see if I can place it somewhere between my streamer and the AVR that will allow me use the audio from the DAC and the video output from HDMI. I figure that I can send both signals via HDMI to my TV, then connect the video via HDMI to the AVR, and run the audio via optical to the DAC, and then to the AVR via analogue RCA. The D10s can be had for $160. If that doesn't suit me I can always use it to hook up my desktop PC (Alienware R11) to the amp.
Or maybe I could just start listening to music through headphones again (in which case I'd definitely be in for the Dragonfly stuff)....but I tend to listen to audiobooks rather than music when walking. And when at home I sit in the lounge room and play music from the TV room (using it as an additional amplifier). The neighbours love it. Particularly the sub.
