Widening my soundstage

Check "phase" (positive to positive & negative to negative) of all interconnects & speaker cables. I've found with own system going back to basics is where problem sometimes lies. Equipment sounds to be better than mine. No problem there. Although you may want to upgrade to "better" speaker cables. Follow manufacturer recommendations and/or plug "speaker placement" into favorite search engine. My favorite is http://members.ams.chello.nl/rabru/speaker.html

What are the demensions of you room, where are your speakers placed, and where do you sit?

First thing I'd do is replace the Monster speaker cable with something of Cardas Golden Cross which is a bit on the pricey side but it'd be well worth it then listen again. I'd bet you're glad you did!

Listen, don't do anything yet! If you really want to get down to it start by ruling out the obvious and least expensive stuff first. Answer the above earlier post. Also give info. on the type of room you have, i.e., sheet rock, plaster, ect., location of windows, location of furnishings and any room treatments you have applied. Then wait for feedback. Unless you have these first principle correct, that is properly placed speakers, listening chair and room treatment, the rest of the suggestions are putting the horse in front of the cart. Get this correct first then look at your other variables. $2,000,000 worth of cabling or equipment switching is less effective then proper set up!

Listen to Ramstl. Also, not all recordings have out of phase signal information, so those will not image beyond the width of the speakers (this is not even considering the height and depth planes; instrument image sizes/prespectives, etc.). A good test CD is called for here. Listen to correlated and uncorrelated pink noise, and voice tracks in and out of phase. My two favorites are the Sheffield A2TB "My Disc", and also the XLO/RR CD..........................The point of good imaging, is to have the entire listening room disappear, so that you are transported to the recording venue. If that venue was not "continuous" to begin with, you cannot expect "realism" thru your system, that didn't actually get recorded in the first place. To assume otherwise is folly, but that doesn't stop lots of people from assuming it anyway.................They also love OH SOOO much, to assume that room acoustic treatment isn't necessary, as long as they can hear some form of phantom center image. That is utter foolishness also. Anybody can listen in an untreated room, but please do not deceive yourself into thinking you are "really hearing something good", because you aren't...........I heard the top of the line Spendors at a dealer's house, in a huge room treated only with plants(his "reference"). He was big on deceiving himself, like so many are....the slap echo was about like that of an airport terminal, or a raquetball court. The silly things people do, and with so much money to boot! It's a travesty!!!
