Hi, I am interested in purchasing the following system to go with my current Harman Kardon DVD2552(?) (Silver/Black DVD25) and would welcome any comments you might have with the same or a similiar system. Harman Kardon AMP: AVR630 or AVR7300 (when available). M&K Speakers: 3 x k17 Front 4 x k4 surround 1 x k10 sub Speaker Cable: Please suggest something suitable? I have had no previous experience with M&K speakers or HK Amps. If you can point me at a review of any of these products that would be really helpful too. Many thanks.
