This is the top of the 2016 standard range Blu-Ray Players. Lowest non-promotional price ever according to camelcamelcamel (though I happen to know this was briefly the same price on Prime Day).
With the exception of the UHP-H1 (which requires you to part with nearly £400) this is the top of the main Sony range for 2016. Big selling points for me are the Bluetooth connectivity and the (not advertised) ability to play back SACDs. Bluetooth works well with my Sony headset.
