Uneven soundstage help, please.


I've got a pair of ATC SCM40 v2's driven by a Musical Fidelity A308 (plenty of power) and overall I'm happy with this combination, given my budget, wife, and listening habits. My system is in an incredibly complex large room, with all sorts of variables in terms of reflection, absorption, etc. And these aren't exactly the same from one speaker to another. I have no choice about speaker placement, given the room configuration.
There's a phenomenon that concerns me, though, that I haven't been able to resolve. In order to get the center centered, I need to position the speakers and listening chair in such a way that the soundstage extends all the way to one speaker, but only three-quarters of the way to the other. It doesn't sound out of whack. It's just a narrower field than I had with my older KEF References, and I wonder if it would sound even better if this was resolved.
Has anyone else faced and solved this? What factors are driving it? I've been living with it comfortably, but I wonder.
Thanks ahead of time for any replies.

The Chase Remote Line Controler RLC-1

I use it for everything, remote control of volume and balance of any source.
Your imbalanced situation, you would also, to control balance for any source.
Remote volume and mute are also a real treat.

therefore, everything goes into the Chase, then Chase to the amp.

Amp, receiver, mono blocks, integrated amp, it doesn’t matter, just into whatever drives the speakers.

IF Receiver: Chase output to any line level input, ’aux’ typically, leave all controls neutral on receiver.

My amp is an integrated amp. Chase is the only thing plugged into it.

CD player direct to Chase’s CD input (skip preamp)

Reel to Reel direct to Chase’s TAPE input (skip preamp)

TT (3 arms) to SUT with 3 inputs. (pass for MM; 4 optional loads for MC)

SUT to Preamp’s MM Phono Input

PREAMP Output to Chase VCR input (very cool record player)

FM built into Preamp, thus also goes to Chase VCR Input.

Cassette and 8 Track (rare, but ....) spliced into Y, then to Chase AUX (skip preamp)

................................

Thus my Preamp on for TT or it’s FM only. Everything else, Preamp OFF, Chase direct to Amp.
You might send everything to your preamp, then to Chase, then to amp.
...............................

VOLUME. Important to get right to properly benefit from Chase’s ’loudness’ circuit.

Chase, default turn on volume, leave there, no loudness is engaged.

Preamp/Amp/Receiver, adjust it’s volume ’ONCE’, for your normal listening volume. Leave it there forever!

Volume Up, use Chase Remote Volume, no loudness involved.

Volume Back Down to ’default’ volume (2 lights), no loudness involved

LOW Volume, down from default, as you lower the volume below your normal, LOUDNESS circuit begins, progressively engaged as you lower.

Primary benefit is to boost bass progressively, i.e. Jazz Bassist. That is what maintains involvement for me, keeps my attention and enjoyment even at low levels. It also boosts the highs, I don’t even think about that, if I want to appreciate highs, I’ll be listening for real.

I wouldn’t live without one.
....................................

Verify it has zero noise, zero detriment to your system. Plug CD direct to amp (skip your preamp, skip chase. Listen. Now CD direct to chase (skip your preamp), chase to amp. Listen. I and my friends hear absolutely no change.

If you do, it you hate it, return it! I’ll bet money you keep it.


Angling the speakers differently combined with adjusting the balance works wonders sometimes.

m669326,

I apologize if I missed it, but what have you been listening to when you have been trying to balance the left/right image in your system?  Has it been pink noise (or some sort of test signal) or specific music tracks?
Larry, I've been using various familiar tracks. Are there specific tests? How would noise help?
I improved things by eliminating toe-out and playing around with the dimensions of everything until the soundstage extended most of the way on the short end without wrecking the center. It's not perfect, but I'm happy with it. The room is so ridiculous, i can't expect perfection.
