@riley804 : I was replying to @bshaw , but that’s OK, it sounds like you also have GIK diffusers you cannot put on wall. Below is the GIK diffuser page. Which one (s) of these you have?

@thyname

when i contacted GIK, they wanted pictures of the room so they could get an idea of what to recommend. if i was to put any kind of panel that they suggested on the side walls, it wouldnt be even as there is a window on one side and a panel would hit the light switch, so he suggested the diffusor that has a stand and can be moved around.

mine is the black and white one, but its 2’ x 4’.

unless i get creative....these are not meant to be hung on a wall as there is no mounting hardware and would have to think of something.         not saying it couldnt be done.... 

i dont think moving 2 panels is going to change anything to be honest.

Those definitely can be put on wall. And come with all the hardware. I know, I have bought many Alphas. From the very link you posted, under Installation Guide tab:

INSTALLATION GUIDE

All (23″ x 45.5″) Alpha Series Panels come with two sawtooth hangers for easy wall mounting.

You have your choice of orientation. 
 

You will actually have to pay extra to buy the freestanding wood kits. If you lost those sawtooth hangers, they can be bought in any hardware store. Unless you don’t want to hang them, or you are not allowed. That’s another story, totally understandable though 

I agree with you, but when I go, once a year or so, it’s giant speakers in giant spaces. (my point being that soundstage is not a given, we are not recreating but creating it)

@grislybutter , gotcha. It’s been like over 40 years since I dropped acid & went to a Rush concert at an amphitheater, but even more recently (which is now over 20 years ago) when I was catching way smaller acts at general admission 500 seat venues (which usually were not filling anywhere near capacity) I wasn’t there for the sound stage and I don’t think I was hearing a whole lot of it; I was there to see an artist that I really liked perform. What I heard in my living room usually sounded better than what I went to see live.

@bshaw , I will thank you for posting this thread. I had been putting it off for a while, but because of this thread I was in the room tonight tweaking the speakers, & I wound up bringing them about 6 more " from the rear wall, incrementally closer together (therefore incrementally further from the sides) & the listening chair moved back a bit. Hopefully I’ll be back there again tomorrow night to do some more evaluating.

A couple of more things to take or leave as you please: but all CDs are not created equal. I won’t ever be critical of anything anybody listens to, but ATTEMPTING to create a better sonic environment & ATTEMPTING to listen critically is what turned me on to jazz (which is not to say that jazz is all I listen to). My small room & what usually seems like probably a smaller venue or studio seem to work well together, plus there is a lot of well mixed and mastered source stuff to choose from. I’ve tried classical, but I think that this is where the small room’s limitations become more evident. Plus, classical doesn’t really float my boat.

This (hopefully) quick story is the last thing I’ll say about electronics: around 25 years ago I was listening to a smallish Cary tube amp (four 6550s for outputs), and a B&K HT preamp (I have long since abandoned HT) & my stereo system utilized a pair of B&W 805s. I read Stereophile religeously & I longed for the sound stage they all wrote about. One month Stereophile featured the Mesa Baron (a dual monoblock in one chassis tube amp, 12 output tubes per monoblock that are switchable in thirds from full triode to full pentode, meters, rack handles, all sorts of cool looking switches . . .) and a local dealer actually had one he let me try out for a weekend! Plus he was going to give me a decent trade in on my little Cary! Man, I was excited about that! He advised I utilize 1/3 triode & 2/3 pentode & most of the time I did. Using the same speakers & without changing their placement I was instantly struck by how close in my face the music was & how it filled the room. I was listening a lot to the the Cowboy Junkies at the time & Margo’s voice took on a husky quality (as did all vocals) & a smoky or musky sounding background was always pervasive. But it was new & different & I initially found it appealing & it was a soundstage & I hadn’t really heard one before so I had just about made up my mind to buy it,

but

the last thing I did the Sunday night before I was going to bring it back or close the deal on it was to hook my little Cary back up & I put the Cowboy Junkies back on & listened to Sweet Jane (it was either off of Trinity Sessions or their only live CD at the time) and the sound stage shrunk back to the wall that the speakers were on, but there was a blackness to what surrounded the music and around the vocals and the instrumental work--cymbals hung in the air & vibrated and I could imagine her clenching her teeth on certain passages & it was like, "that other stuff was neat in a different sort of way, but this is clean & pure sounding." So I kept the little Cary (I still have it) & gradually upgraded through a couple of more amps & a couple more preamps and wires & cables & digital front ends.

There was a point to that seemingly pointless story, but anyway, good luck on your quest. Ramble on. . . .
