B&O used to be an innovator -- and have produced some beautiful looking stuff.
But (as above) they are more noted for clever controls and pretty boxes than for sonics perfection.
Just bear in mind that they are (still ?) strongly associated with Philips who aren't noted for their sentimentality towards brands' heritage so recent products may not be so great.
Also check if the unit you're considering uses DIN connectors rather than regular RCA/phono sockets -- DINs are a pain if everything else you own is phono plug.
