Looks like a great price for an excellent brand- £299 from Richer Sounds (or £330 with 5 year guarantee) plus £6.95 delivery (or you can collect)
Selling for £350 on Amazon (and without DAB according to specs on Amazon!), £420 at SuperHiFi or £499 at Absolute Audio.
Reviews I have seen have been excellent- and sound quality meant to be exceptional for such a compact unit.
I will post technical specs in following post. Info also from Richer Sounds website:
For nearly two decades, now, Denon have been at the forefront of the quality mini system market. Very few can combine quality sound with style and compact dimensions quite like Denon can. For proof of this you need look no further than the S81.
Within its compact casing, the Denon S81 manages to pack in a powerful, digital 50 watt amplifier, DAB/FM/AM tuner and a flexible CD player. Also included with the latest Denon mini system you'll find a pair of specially tuned speakers. Although similarly compact, thanks to special tuning, the sound quality is anything but - expect a tinny sound quality and you'll be amazed by the S81's depth and scale of sound.
Enhancing the S81's flexibility, the CD player will happily play MP3 and WMA discs. Furthermore, with its built-in DAB tuner a huge range of digital stations are available. Both CD and radio are well served by the comprehensive, twin line, blue display. As you'd expect from a modern all-in-one system, the S81 features, amongst other inputs, a special iPod connection.
With its clean styling and wonderfully simple control layout, the S81 manages to hide its wide range of features well. Finally, thanks to your friends at Richer Sounds, this luxurious Denon system is available for less than ever before. For a complete solution, you won't find better at this price!
