Apologies if this is a very simple question, but I currently own a Denon DHT500SD home cinema DVD system and am still using the thin freebie speaker cable. It still sounds pretty good but I would like to upgrade this to some higher quality cable to get the best out of the system, but space is pretty tight at the back of the player. At present the freebie speaker cable is inserted directly into the spring clip speaker terminals. I'm not sure that a thicker cable can directly be inserted into the player via the spring clip speaker terminals (it'll just fall out or not have room to go in the first place). Are there special connectors that I can put on the end of the new cable (say Monster Cable speaker cable) so that it slots in to the spring clip speaker terminals? Thanks
