Great idea, a bit steep in price but yes, I can see those catching on.
My mum bought a Rigonda Bolshoi Stereo Multiplex back in the day (70's) - a superb 'gram' - (such grams sounded good in the day most of them valve driven only to be replaced by the crap of the 80's like the Amstrads & sensui etc of that period).
it had a seperate pair of 3way speakers containung an 8inch woofer, 6inch mid driver and tweeter in a cabinate standing about 80cm high, 20cm wide maybe about 20 cm deep - it sounded superb to my young ears genuine hifi back then..
if the price is right they'd make alot more sense than the Docks I've seen and could well produce a far superior sound
