As an owner of the NP30, I am not over impressed with what you get for your money. I await the WhatHifi review with trepidation. I hope it will not be another glowing review claiming 24-Bit .wav wireless streaming, which of course it will not do. It has a very mediocre Wolfson WM8728 DAC, with a dynamic range of only 106dB, with a THD of -97dB.
I find the UI very clunky, with down the only direction of travel allowed to the bottom of a long list of files or stations. The UuVol portal is just as clunky. For instance, if you execute a search for a genre of stations, the returned result is presented as a random mess instead of alphabetically. Should you want to save a station, there are only 20 preset memories for all your stations and podcasts. NO favourites list.
Not a lot for £400. Should you actually want to listen to it, or to have a clock display or alarm, it's another £400 for the matching tuner/amp and decent speakers.
