The MR1 is a delightful little Bluetooth speaker, well made, nice desktop sound. Just ridiculously priced.
But then so are pretty much all the lifestyle/computer/desktop systems produced by all the 'hi-fi' companies, the Wharfedale has the advantage of being cheap and cheerfull though.
A lot depends on how you want to drive them, if you have a decent analog output or are prepared to use a cheap usb dac, there are a number of quite potent active monitors available around the £150 mark or even less.
