Combine (this receiver + DAC + amplifier) has reached the suburbs for 13 days, i.e. relatively quickly. I connected it via the Android app 4 stream without problems, although in the reviews and write that there is a dance with a tambourine on Android and I even prepared iPad in case of war, but no, everything went well. I bought to replace the drain amp microlab Pro 3. God... how he plays on these cheap speakers! Listen to tuneln or muses. Collection with Nas by DLNA and I hope for an early arrival in the Russian Federation Spotify, that's when it will reveal! PS. There is a certain proportion of dependence on 4 stream in terms of the quality of software implementation and usability of the program is not the most chic, but it is a kind of investment in what will be completed in the future. PPS. They write that he is weak and can not shake acoustics-it's total nonsense, the gain is enough, and for the apartment I will definitely take S10 to the bedroom and S50 to the hall, as a preamplifier, to be a multiroom. In the first second of unpacking, I was unpleasantly surprised to see the shabby front glass panel. Well, I think that's okay, with him. But then in some review I saw that they shoot the film. Checked-the film on the spot)) it was so qualitatively glued that the full illusion of poor quality grinding. Manufacturer-you for a note!))
