Your most indispensable "tweak"?

I find it amazing that the exact same products could have such completely opposite results in two different systems, I must admit, I’m stumped.

Reagrding the CMS, they absolutely just blew me away. They made such an improvement I just couldn’t believe it. I had the same result (admittedly not as huge but pretty damn close) when I put the Denali v2 in the system. As you know, the Denali v2 doesn’t ship with a power cord. When I opened the box I found this out. My brilliant dealer forgot to mention that little fact to me. I called him up and asked him what the cheapest 20 power cord he had in stock just so I had something to use until I could figure out which really good cord I would get. He sold me a Shunyata Venom cord that retailed for $250.00. The blow away results I’m getting with the Denali v2 is surprisingly with that cord! Talk about bang for the buck. I am going to eventually put one of their Sigma XX cords on the Denali v2, should make a significant improvement over the Venom. Take care.

Hey All,

Over the counter...inexpensive...effective for wax "producers" ...better than having "dry ears" btw.  https://www.debrox.com/

Controversial, but do some research...I have just completed a full dot application of my Music Reference RM-10 MKII.  Here is how I shared results with my audio buds:

"25 years ago, my local Tech (Rick), now retired to Florida, was doing deep dive experiments around resonances, macro and micro, including electrical resistances. He possessed the technical and listening skills...plus the extreme patience to become expert in applying the VTS Dots. Yes, you can harm the sound, easily reversible. He referred to it as "opening up the sound," probably the most apt description.  
So, what's my result? Bloom was the first thing that came to mind. A maturation of the system. Clarity and greater honesty of the timing of events, like live. Less congestion of massed instruments and chorus with an enhanced sense of space and time, enhancing the holographic ability associated with great tube playback.
It's not by chance that the esoteric high end is finally paying extreme attention to floating circuit boards, extreme isolation racks, layered and exotic materials for loudspeaker enclosures and feet. Turntable designs are off the charts identifying and addressing plinth, arm, headshell and stylus resonances
It is a shame that these lightweight, layered music makers have been largely ignored by our industry. Proof's in the pudding."

So I picked up a novum pmr premium resonator on the basis of a recommendation in this thread (and other reviews) and the effect it has in my room is beautiful. Hard to describe, but improves tonality, image density, without any negatives. It's also quite beautiful to look at sculptural. I've since found a second one used and am waiting to receive it. Definitely got me more open minded about "tweaks". Love all the ideas here. 

I have to second the Critical Mass footers.
I put a set of 4 of the 1.0 under my Lumin X1 and I am wowed. 
I then ordered 2 more sets for my mono block amps.
