thanks for the suggestion. so audyssey seems really that important?
what if i include the marantz SR7010 here? still denon and yamaha?
Audyssey, Ypao, or Mcacc??? what's the difference? since they all auto calibrate right?
It is, in the sense that low frequencies are influenced by the room a lot. So in order for bass to be reproduced accurately at your primary listening positions you will likely have to do a lot of manual adjustments and/or crawl your sub(s) to get optimum performance.
The 3 EQ systems you listed all do auto EQ but they do it differently and will likely yield different results. I have only used Audyssey and I found their newer version, the XT32 with Sub EQ HT capable of doing a very good job in my room, noticeably better than the lower XT version without Sub EQ HT. Some people who tried both Dirac and XT32/Sub EQ HT reported (on forums) that while Audyssey worked well, Dirac was much better. Are they important or not, only you can know. I think it is important because I am for accuracy, not what I like or not like. My goal is for HT to sound like what I hear in cinema and for music to sound like what I hear in concert halls and if Audyssey can help me in that sense, then it is important to me but that's just me.
The SR7010 is very comparable to the X6200W, the feature set is slightly different and their power output ratings are marginally different. If either's feature set meet you need, you can just go for the look and prices you prefer.
