I agree.
I have two Bsnd 1's and they are used daily - one mainly for Radio 4 ( speech based UK radi ) and the sound is superb.
Truth is, it should have been updated for CD/mp3 capability years ago and adding a USB/SD input can't be beyond those clever Danes - given every £80 bit of plastic crap has one built in, they can't be too costly.
Better still - why not just replace the CD mech with an ipod dock.

Doesn't sound (quite) as good. But there's a lot of tech in there. Half the size. One third the price.
Importantly - it suggests the basic form is appealing and saleable.
Its a shame... but when BSnd 1 launched it was £590 - it's now about twice that - so perhaps it is inevitable.
