so i brought the Pioneer 82TSX home for a couple nights to compare against my current Yammy V659.
my first impressions were decent. its much more aesthetically pleasing than the Yamaha but i already knew that. there are quite a few more steps in the automatic calibration process which i liked, but i already knew about that too. then things went downhill a little.
one of my concerns with the yammy was the fact i have to turn the volume so high to get the sound levels i so crave now and again. needless to say on first test (ipod-yes i've read the articles about how terrible compressed music is - but i'm hard pressed to hear any difference in a CD) i found i had to turn the pioneer a few db's higher to achieve the same sound. and due to the auto system setting all my speakers to large etc it sounded like crap! so i switched the input to cable, xbox, etc and all were the same, i had to have the unit a few decibles higher to get the same sound levels from any source.
so i went and checked out the details of the auto set up and set my rears to small. unfortunately i cant find (mind you i dont have the manual - i ended up with a french one-DOH!) many other familiar settings, ie: LFE output, equalizer, etc... the equalizer settings i can see are very complicated and seem to be for individual speakers, i would think there must be some kind of general adjustments.
so one my first eve i was somewhat on the fence as to wether i liked it better or not, but things did get better. one thing i did like better was the over balance of sound. the bass was much tighter with the rest of the speakers, and sounds seemed to travel smoother from speaker to speaker. and i also knew there were many adjustments to be made to improve the overall quality that i just have yet to figure out.
yesterday i hooked up another set of speaker wire to my fronts as the Pioneer is able to Bi-amp, so i thought i would see if that makes any difference. it did. i hear life, and bass from my fronts that i have never heard before. it made them a little bit louder but more so made them sound much fuller. i found this imporoved the overall quality from all sources putting it now noticabely ahead of the Yamaha.
so now that i've monkeyed around with the DSP settings quite a bit with different sources, and found ones that i think are best (without having read the manual - i'm sure i can make it WAY better once i know how to)
i definately prefer the sound quality of the Pioneer. most noicable is how much better balance the surround sound is. sounds from behind me are much more prominant yet the centre voices are never drowned out. as mentioned the sub is actually in unison with the rest of my system which makes a big difference. i now find explosions sound more realistic, and again are much more balanced than before. ie: when playing Call Of Duty 3 on my 360 in order to get loud surround effects i had to have it loud enough that an explosion would blow the pictures of my walls! with the pioneer however, while the explosions are loud, it isnt too much.
music wise, i also prefer the sound from the pioneer. not only do my fronts sound much better in 2 channel stereo being bi amped but the 7 channel stereo sounds AWESOME due to the much superior calibrating job the Pioneer does. i will say i think the Yamaha's compressed music enhancer does a better job (again there could very well be some feature on the pioneer i havent found yet) than the pioneer. also with the pioneer you can hear the hard drive on the ipod spin through the speakers when you change tracks, while it isnt loud, nor last longer than a second, it is a little distracting if the song you are flipping to starts quietly. what i do LOVE about the pioneer is its superior control function over the ipod - you can flip by page instead of one track/artist at a time! the yamaha was painstakingly slow as it literally took about a second and a 1/2 to flip from one title to the next, so needless to say ZZ Top and Zwan didnt get much play!
so i've pretty much decided to go with the upgrade, and sell my yammy to my buddy. the yamaha really is a great amp, but the pioneers ability to bi amp and superior auto calibration are the deal breaker for me. not to mention it matches quite nicely with the 60" Elite Plasma i just got!
