Power cords or power conditioner

2 1/2' off the front wall may not do it.  I'd try moving your chair back and moving your speakers out more from the front wall.  I had a similar problem and this helped soundstage depth for me.  Nice system btw.

Room first for sure.

I went with Shunyata power conditioners and NR Shunyata power cables. This changed dynamics and texture, but I don’t recall a big change in soundstage. There was a better image but not an expanded soundstage...like more air surrounding the vocalist. What I did with power was to purchase with 60 day trial, but in my system and with my power the Shunyata products worked for me.

The power cord to your amp will likely have a large impact. Given what you are attempting, I recommend trying an AudioQuest Hurricane. I would borrow or rent. These have become extremely popular because of their ability to add transparency and detail without negative impact of the bass of changing the tonal balance. They had a huge impact in my system.

A power conditioner is going to be more challenging for you with an integrated. Almost all power conditioners have a negative impact on current flow… so amps are usually not plugged into the power conditioner… but straight into the wall (direct line will also help). But the preamp and all other components plug into the power conditioner. Without the preamp plugged into the power conditioner you will not get as big a position effect from a power conditioner.

But to address your problem. Each of the things discussed will make a difference. They are additive! This is key. You may have to do all of them and slowly work step by step to get to where you want to go.

You want direct line/s

You will get greater transparency through Transparent Ultra… although at greater cost. The new generation are better than older.

Careful running of cables… 90 degrees at crossing. Cable lifters.

I would pe patient… just slowly work one thing at a time and get it right. It is very likely you will get there.

My money is on a exhaustive speaker setup/sitting.Nail that and the rest is the easy part.Should be able to achieve some level of what your desiring.I went through this last 2 week’s,I havent had a power conditioner for years.Cd and amp straight to wall socket.It has produced some great results.I have a great sound stage before the addition of conditioner...as George said it just add’s that element of a "cleaner" signal... and fwiw mine will stay in for now i believe

Thanks guys!  I have DYI power cords on all my two channel equipment.  I used Oyaide Tunami V2 for the cable.   Not the best but far from the stock wire. So my power wires are not bad, just not up to reference level, if that is needed. 

As to speaker placement, trust me, I'm been playing with the placement for a year.  I've got them where they sound pretty good.  I did pull them out another foot from the wall today.  It did help give more dimensionality to the sound. 

I have an 80" TV in the middle of my sound stage so I tossed a thick blanket over it and it helped.  My center channel KEF Reference has a large aluminum face so I tossed a blanket over that next.  Helped a tiny bit more.   I think I'm on the right path!  😂 Total spend for improvements today- ZERO.
