I've recently thought about a 5.1 or 7.1 system and started my investigations: Since hearing some Gryphon active speakers many years ago;I promised myself I would buy some if I ever re-equipped. My researches indicate that ADAM active speakers are good and affordable, The problem arises as to how to connect 5xadam A7s with a 5 channel preampwhich will decode the digital signals from my sky HD box and blue ray disc player/recorder. I am told that a Denon or similar AV receiver can be used as a preamp to distribute the 5/7 channel signal from HDbox/blue ray player. Stand alone preamps for blueray/HDbox channeling are not yet available;although I'm told that Arcam will market one soon at about £7000(they must be joking? I would be grateful if some erudite AV freak could tell me if these ideas are possible or nonsense? I would also be grateful for any cabling advice? Thanks for reading my little missive!
