Ethernet Cable or Not?

Hey everybody,

Thanks in advance for your guidance.

I use an inexpensive WiFi receiver to send a signal to a Schiit Dac, then to my Integrated.

The wireless signal never lags/buffers, but sometimes music sounds better to me than others. Very well could be in my head, tinnitus intensity, etc.

Line of sight to my router is approximately seven feet, and a ten foot cable would do the job and for the most part be hidden.

Is a wired connection between a router and WiFi receiver the way to go if one is possible? Or if I’m not having buffering should I let it be? (I don’t own a cable to try but can pick one up if it’s likely to help of course.)

Thanks for the help!
Additional clarifying points.

1. You are already isolating your ’router’ from your "WiFi receiver" by using WiFi. This is a good thing.

In this scenario, a single LPS to your "WiFi receiver" is a good first step.

2. IF you choose to run ’wire,’ i.e. the LAN cable from your ’router’ to the "WiFi receiver"....

Then, powering your ’router’ with an LPS becomes more critical...for the reasons @almarg highlighted in his post.

Having a LPS that can power both is ideal and also allows you to test cable vs WiFi (to determine which one you prefer).
Uncle D, if you are going to try a quality ethernet cable I suggest an Audioquest Cinammon. It's not real expensive and it made a noticeable difference to me (over generic) that I liked.

Quality of cable is important but remember that you are working with 1000baseT, not 10GbaseT. That means you can achieve perfectly good results with well-made cabling that is rated for 1000baseT, which CAT5 (not even CAT5e) is rated for. The benefits of higher category cables are lower near-end crosstalk and (in certain categories) better common mode interference rejection and lower loss due to capacitive coupling between pairs. CAT6a (augmented) is called for on restricted runs for 10GbaseT, so forget about anything beyond CAT5, 5e and 6.  Buy factory made patch cables that have been certified by well-regarded manufacturers such as Leviton and Hubbell. Above all, don’t waste your money on “audiophile grade”  network cables - they are overpriced and may be lacking in quality and longevity, especially if they are made of solid core cable, which does not accept crimped RJ45 plugs very well. 
A big advantage of Audioquest Ethernet cables is they honor the inherent directionality in wires just like Audioquest speaker cables, power cords and HDMI cables. Not to mention they employ high silver content connectors. In other words they’re a couple paradigm shifts ahead of the commercial grade stuff.
Thanks again, very good points!

I’ve looked at some LPS options and they can get pricey. Please recommend a cost effective option if you know of one, I may be overthinking this.

Also, If I upgrade my WiFi receiver to a Blusound Node2 would that be a big step up, or would the LPS still be needed?

Thanks and regards-
