I'm having a little trouble getting my Marantz 6014 consistently sounding the way I would like. It may just be the source material as some things sound great, but other things not so much. I was wondering what benefit REW might have over just using the Audyssey app and if there is a good explanation somewhere that anyone is aware of on how to use these tools (bith the audyssey app and REW) to best effect. I have looked and see a ton of things online, but some of the information is either not particularly helpful or suspect and I would prefer to get a recommendation about something that I can feel confident is actually accurate and reliable.\n\n\nDon't expect software to analyze and fix problems without being much more full-featured- it's not for perfect sound, it's for better sound.\n\nIn order to make a room and system better, more extensive understanding of what's happening is needed- all REW does is show what's happening, not what to do about it. \n\nREW is useful and accurate, but within limits. Is the mic accurately calibrated? If not, don't expect miracles. Have samples been averaged over a large area? If not, don't expect miracles. \n\nSpeaker placement and some balance of reflective, diffusive and absorptive surfaces is needed- without that, there's not much hope of getting great sound- equalization only fixes part of the problem.
