How do I get the best soundstage?

Get Jim Smith's book titled "Get Better Sound."  Read it, then sweat the small stuff.

@hysteve :

I’m not aware of the place to load a photo of my system but I will look into it and see if I can.

You can post pictures of your system (and info) here: https://systems.audiogon.com/

Azimuth, azimuth, azimuth. Correct azimuth provides maximum separation, the critical step in sound-staging. Small adjustments can be heard.

All these folks are telling you many things including how to spend your $$. Fact is, if it doesn’t come off the disk properly it will never be at its best. A VPI set-up will provide a means for adjusting azimuth. Set if first carefully by eye. But learn how to make small adjustments in it and set it by ear. A VPI Dual Pivot Assembly will make that far easier, improve tonearm handling and even SQ. That’s the very best way. You really don’t need expensive set-up stuff.

@hysteve you said...

I have a better than decent digital system. I.e. Pass integrated amp, Innuos streamer and USB reclocker, Ayre DAC with Less Loss power cable and firewall, Volti speakers. I’m my dedicated listening room the digital system is sonically superb to my ear - Except that the soundstage is ok but not the best.

Adjusting the amount of Toe-in might help or perhaps tilting the speakers back a little?

I think your interconnects and power cables should be fine

I’m still thinking it’s the speaker cables

• I have used similar types of speaker cable and by comparison to more modern cables that employ a significantly better cable geometry, that style of speaker cable will not perofrm to the level you are seeking
• I would look at Zavfino, or In-Akustik speaker cables
