Can't help you out on this one but I find that the Argos catalogue is a good place to compare specs & prices. Helps me to clarify what I actually want.
€300 sounds a lot if you're just going to stick it in the kitchen etc & listen to it while cooking dinner. Do you need a cassette player & bi-amping is probably useless in a product like this.
For a little bit more, you could probably get 'proper' HiFi separates.
