Practically, every equipment will work with SACD with its passive filter in "standard" mode. In some models you can move this filter to 'custom' mode which is increased bandwidth. most people find that sacd music at this setting is better or much better. However, you dramatically increase amount of noise produced by noise shapers in the area above say 40kHz. You MUST speak with your speaker and amp manufacterers to find out if it can damage your equipment (e.g. to fry your tweaters). Practically every manufacterer does not afraid this hi-freq noise but its safer to ask. Next, since SACD produce signal in the range of 20- filter cut-off frequency (say 60kHz as in 777es) then theoretically its better if your equioment bandwidth can carry such signal. However, most tweaters on market, including mine handle up to about 25-30kHz only. If you like its performance don't exchange good sound for good spec. Best wishes. When you get your SACD and wait a few weeks for break-in, you will feel that you are in paradize. Good luck - Simon
sacd help please
I admit to being quite confused on what type of equipment can fully take advantage of sacd, both two and multi channel. Of course, Sony is particularly useless when it comes to explaining what equipment is compatible with what other equipment. I currently have a Lexicon MC1, and old sony es theater receiver and a Parasound 2500 processor. I do not know whether any of the sacd players or changers, stereo or multi will work with any of them or what I need to have for a processor to work with sacd. All comments are welcome.
