Merlins VSM placement question


Hi all,
I currently own a pair of VSM-MXe for a year now - Very happy with them after trying different front-end and preamp/amp
Despite swapping gear in/out, I notice that the soundstage is always somewhat narrow, too focus at middle (same plan with speaker).
My room is 23ft long x 16ft wide x 10ft high
Speakers are 7ft apart and 5ft from front wall (16ftwide wall). Listening seat is 7.5ft from speakers plan
The whole set up is 1.5ft off to the right of center axis of the room (due to door access)

I followed exact Bobby's instruction including toe-in angle using included tool

My question is did you're Merlins' owners followed exact set up instruction from Bobby, regardless of your room's dimension ? What's your placement dimension?

I want wider and deeper sound stage, not too forward
I have a feeling if I move apart extra 1ft between speakers, or set up the toe-in 3ft behind the seat, I would change the sound stage as I wanted

I have Jim Smith's Get Better Sound with me, but I'm kinda lazy unless I can see if it's worth the sweat

PS: I have tried Cary all-the-way (SLP05+CAD120S+306/200) with CGRs, and Sony 5400ES + ARS Sonum - with same stage sound
Please advice
Thanks

all these discs are not made of brass and not all brass has the same lead content.
right you are paul.

tvad, paul was talking about some disks that are not brass and the resulting decoupling.
and the amount of lead in brass will have a lot to do with how these sound under your speakers because of their q and their specific needs.
nothing implied. interesting discussion though.

I never A/B'd different footers, so I can't say what if any differences I would here. I went with the APs because they specifically say that they couple the speaker to the surface beneath them, rather than decoupling them (some of these brass cups claim to decouple. I don't understand any of this other than to say Bobby mentioned I should not decouple the speaker from the wood floor, I tried the APs and think the speakers sound wonderful. Whether other brass cups would sound any different, I have no idea - I only know they work very well in my setup and keep those viscious, sharp spikes off my floors.
