Equipment Rack Between Speakers...Good or Bad

This question came up in another current thread and I thought it would be more appropriate to start a new thread to address it. My rack is between my speakers. In the past I have tried it off to the side and didn't notice any sonic advantage. I have seen in in the past that there are some strong feelings on this subject, and I am interested in hearing what everyone has to say.

I’ve become obsessed with trying to make my smaller/square ~13 x 13-ish room sound bigger and better.  Installed bass traps, and diffusion/absorbers on side walls and rear walls. All have help tame bass, balance things out, improve decay, and liven up the room some.  My next step was to experiment with moving my rack from the center of the speakers over to the sidewall.  Even with a cheap $20 Amazon 7m balanced cable run (displacing my Anticable preamp to amp connection) the soundstage improvement was immediately noticeable.  Beck is now standing 6’ in front of me - I was shocked how much of an improvement there was.  Why didn’t I do this sooner?  For those of you already curious, esp if you have a smaller rooms, I highly recommend giving it a try if you can.

If your system is a lot of work to move and be set up for a while I use my audio analyzer and run some noise through it you can walk around with a calibrated mic and look at the frequency response in different parts of the room it won't show you much if there's phasing issues

So, for those of us who don't want to move furniture around just for fun or experiment, what's best?

No furniture between speakers to preserve image or some furniture in-between to break up standing waves?

See my Virtual System with pics before vertical rack in between and replacement with a low profile solid wood table in between: HUGE improvement
