I'm looking to buy some decent HiFi speakers and at the moment, despite being a 5 year old design im looking towards the q acoustic concept 20's as they have great reviews and I will get a £400 set for £200 new. However I've been looking for a while and keep getting drawn to high end speakers such as Dali rubicons which, really I can't afford however, how much better can the top end speakers be? I suspect like most things, there is a price point where cost no longer returns the same benefit gains. I'm sure all components are better in the top end speakers but do they warrant the price, especially when room acoustics could kill the additional performance. If I though the rubicons were 10 times better than the concept 20's I would buy them as it would be a purchase I could justify however, they can't be that much better, can they?
