I am thinking of buying an REL Strata III - my Hi-Fi amp is a Cyrus 5 and I also own a Sony DAVS800 system. As these REL beasts are rather expensive I would quite like to use the REL in both the hi-fi and home-cinema set ups. This would mean replacing the DAVS800 subwoofer (which is linked via speaker wire) with the REL. The Sony manual says do not use any other speakers with the system but they would say that wouldn't they ?. Any ideas if/how I can do this would be gratefully received.
