My Pure Siesta arrived yesterday and I'm very happy with it!
I recently bought a Pure ONE for the kitchen, which is excellent too. Pure seem to have taken the best bits of their more expensive, wood-cased models, and put them into plastic cases for those of us who want quality but don't want to pay quite so much. You don't get quite the same looks, but the sound from both units is pretty damn good, especially considering they're mono units. They're better with speech, with a nice, warm sound, but they don't disgrace themselves with music either.
The Siesta looks great, though the display is the one thing I'm not completely in love with: the clock is just slightly too small for peering at in the middle of the night, and being a backlit LCD it's less than readable when looking down on the unit from above. The scrolling text display is a bit "jumpy" too, though it can be set to display other things if it annoys you.
There's a headphone socket at back on the top, so if you want to fall asleep to Test Match Special without disturbing anyone else, you can!
Sensitivity seems to have improved a lot since my first DAB radio a couple of years back. Both the Siesta and the ONE pull in everything on the London multiplexes, even in our basement (in the ONE's case even with the aerial down!) at nearly 100% signal quality, whereas my old radio couldn't even do this with the aerial up... in the garden...
I read a review elsewhere from someone complaining that the alarms were tricky to set. The process is a bit "involved" but very logical, and the flipside is that you get a lot of versatility: four alarms, each of which can be daily, weekdays, weekends, Saturday, Sunday or once only to eiteher DAB, FM or the beeper.
I was a little disappointed that, given this flexibility, it's not possible to set which station you want to wake up with and are stuck with the one you last listened to. So, if you want to drift off to sleep with the Shipping Forecast on Radio 4 and wake up with Chris Moyles on Radio 1... you can't. Nor can you get up to one station and your partner have a lie-in and wake up to something else an hour later.
I'm sure this kind of thing can be changed later if enough people want it, and the Siesta, like most of Pure's new range, has upgradable software via a USB port using a PC (but not a Mac, unfortunately).
One small point: the DAB we currently have in the UK will eventually be superseded by DAB+ using a more efficient audio "codec" (HE-AAC v2 as opposed to MPEG1 Audio Layer 2, for those who are interested). Though most existing DAB radios aren't compatible with the new DAB+, DAB transmissions will continue for many years to come. The Siesta has been designed so that it can be upgraded to the new codec at the appropriate time (though sadly my ONE can't).
All in all this is a terrific radio for the bedroom and the worth every penny. It looks great, doesn't take up too much room and goes more than loud enough for most bedrooms.
