KEF Reference 4

Can I use the REF 4 for my Cary 572 or Mac MC240?
Need your input?
No, they are not compatible. :)
The kef 4.2 is superb if rather large and heavy and mean heavy! woould have thought that the suggested cary amp would make a very good match. Use a musical fidelity 270.2. present room is smaller than your own and looking to sell them and get a pair of 2.2
