I have noted previously on this board that I have the Bose 321 kit. It is, in my opinion, the best on the market at a cost which is within reason.
If you contact Bose they have a 30 day free trial system which you should take advantage of - assuming it operates in Ireland.
If you have the opportunity to come over to England you should go to Bicester Village in Oxfordshire where Bose have an outlet shop where they sell the kit which has been tried and returned. It is checked and reboxed then sold at a discount in the order of £400, so it could be worth your while checking it out.
