I was looking at the Rose - gorgeous and well made item. I decided I wanted a separate dac and steamer. Alot of people go with a lower priced streamer due to the ever changing environment for software and apps as well as other factors . . . and put the money into the DAC.
Some DACs have a analog input that accepts an analog signal into, such as from a TV or AVR. Some Benchmark DACs have this feature so you can pull an audio signal from the tv stream into the DAC and then send it out to amp/speakers while still preserving the two channel audio path.
