It serves as an affordable, high-end "digital bridge". It allows audiophiles to add modern network streaming to any existing DAC or vintage amplifier without forcing them to buy a completely new system. Features an old-school RS232 control port. This allows users with older, non-streaming Primare amplifiers or home theater processors to plug the NP5 in and control the entire legacy system's volume, inputs, and standby modes right from the modern smartphone app. : Reviewers at Stereo+ noted it delivers a remarkably clean, distinct, and accurate digital signal compared to more mainstream, plastic-chassis alternatives like the Bluesound Node.
