Most useful tweaks that are sensible and really make a noticeable improvement


So after reading the thread of useless tweaks I'd  be interested the communities opinions of useful tweaks. I may be rehashing a previous thread but times change as do useful tweaks.

I have found that in my case the following were useful, immediate and audible,
In order of priority in my opinion
1 Room treatment
2 Speaker location, ie proper setup
3 Subwoofer location (if used)
4 Subwoofer integration
5 Component isolation
6 Cables, all SC/IC etc, normally I would not mention cables but did have an ear opening epiphany that makes me believe cables are system dependant and I do not mean directionality.

So if anybody has anything to add, please do so as none of us are ever too old to learn.

Obtain exact level of the CD to reduce tendency of the disc to wobble whilst playing, which is not good for quality of laser reading, especially in light of the fact CDs are frequently out of round. However, the level of the top of the CD player may not be the same level as the CD. What to Do? What To Do? 🤔
My tweaks
(1) Isolate anything that has moving parts - Turntable, CD player,
(2) Isolate anything with tubes.
(3) Be fastidious with Speaker and Turntable setup.
(4) Every 3 years or so clean all contacts with Caigs Deoxit.
(5) Make sure your cables are tidy - for example don't have interconnects running in contact with power cables.
(6) Prefer long interconnects with short speaker cable to short interconnects with long speaker cable if possible.
(7) Avoid MIT cables.
(8) Use Dynamat on speaker driver baskets and non visible parts of the turntable.

Be sure to clean all non-audio wall outlets in the house. The noise on audio circuits includes noise on other circuits. You know, things like micro arcing.
Noromance: In an urban setting, removing the cover of a preamp virtually guarantees you will be hearing ham radio instead of your music. That was my experience.
