Power cords or power conditioner

OK. Fair. Nothing you said is essentially terribly wrong. Show me your room & your room treatments and I will eat crow. You can PM me or post a picture of your system here under “systems”.

also:

But I am more of a cable denier

The good thing , again, is admit this 😂

And for some reason, you folks believe that people who spend $1,000+ on a power cord do not take care of their room and the room treatments and speakers positioning 🤦‍♂️🙄

You quoted me on this:

From my own experience with real people, those who proclaim power cords and conditioners make zero difference, and room is all that matters, typically have zero room treatments in their rooms. They just love to bash cables. As they say, don’t pay attention to the preaching of a naked priest. Or something like that.

Let’s just leave it here:

Once the OP sees if anything helpful can be done with speaker placement, then they can do the power cords.

My main statement was that I would do the easy stuff first.

Since we seem to agree on that, let’s just stop there for now.

Great sonic improvements were made with a dedicated 20A circuit, a PS Audio PowerPort Plug, and a good power cord to my amp. Did try plugging my amp to a Panamax conditioner that I use for low current components, it was awful.

I recently replaced my stock power cables with Cardas Clear Beyond to my Electrocompaniet AW400's which run Kef Blades and I and my wife noticed a definite improvement with what you're looking for. Yes my room is already treated.

I would start with speaker placement and room acoustics. What’s on the floor between you and the speakers? Place an area rug if you have bare floors. 

Move speakers to be about 4ft from the front wall. That should deepen the soundstage. 

Treat first reflection points at a minimum since you already have bass traps. Diffusion or absorption on first reflection points should help widen the soundstage. 
GIK Acoustics panels work pretty good  

Power conditioner on source components should also help. Depending on how dirty your power is, lowering the noise floor will help the details emerge out of a much quieter background. You have decent power cords but it wouldn’t hurt to experiment. If you’re changing the power cords tackle the amp cord first.

I’ve found higher end Audioquest Storm series high-current power cables on power conditioner and amplifier make a nice improvement in my system.
I’m using AQ Hurricane on power conditioner and Tornado on amp. There are tons of other options you just need to try…after you get your room acoustics squared away. Just my thoughts. Have fun and good luck!
