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

Paint both sides of an fo.Q RS912 turntable mat with 2 coats of AVM (anti vibration magic). Unfortunately AVM is no longer commercially available, but I obtained 17 bottles of it 3 months ago, by asking around. It was semi-solid but I managed to revive it by mixing with water and squeezing it until it came back to life.

Said fo.Q/AVM mat adds incredible inner detail and depth when playing LPs and 45s.
If anyone has spare AVM stock for sale, contact me and I will buy it at full price if it's still liquid. Must say "Made in Canada" on the front of the box. If it says "By Uniko" on the front, it's old stock and probably solidified.

If you can’t afford fancy fuses, wrap the middle of an ordinary fuse glass with a 5mm strip of piezoelectric tape, then paint the tape with everyone’s favourite graphene paste.
Assuming you may already have leftover ingredients on hand, the cost = $1 for fuse + 30c for tiny strip of tape + 20c for tiny TC smudge = $1.50

E=fo.Q+TC²

“Seems to me actual real tweaks really are those that make sense.”

No, no, no! It’s actually the opposite. The best tweaks, anyway. People need to be a little more open minded. I’m not suggesting they be so open minded their brains spill out on the floor. Break on through to the other side!

With all due respect, Geoffkait do you ever sleep? Broke thru to the other side eons ago. Thankfully found my way back. Senseless tweaks are snakeoil designed to part the gullible from their available funds. A fool and his money..........! 
Now that's not to say that an unconventional tweak could not be worthwhile.  Let's take Geoffkait springs, unconventional yes but a possible sensible tweak. Would I buy before try.......no but with a 3 month money back, no question asked return policy sure why not.
I would even buy at a sensible cost which his springs are not.
Tweaks must make sense.
Ps. Did you know rubbing bacon grease on your cable ends or connectors will eliminate any sibilance in all applications?

gillatgh, ….."Ps. Did you know rubbing bacon grease on your cable ends or connectors will eliminate any sibilance in all applications?"

gillatgh, that is ridiculous, haven’t you been paying attention to Geoff regarding the degradation in CD sound due to stray laser music signals? What you need to do is coat your CDs with the bacon grease. You can experiment with plain, maple or hickory smoked to determine the best impact on sound quality based upon your musical preferences. Personally, I find the hickory smoked most pleasant with jazz recordings.

Feel free to eat your bacon after completing the "bacon grease extraction tweak". As with all tweaks, we all know you need to have a very resolving system to hear the sonic improvement, so if you don’t its because you have a mid fi system. My audiophile friends with golden ears and 400 years combined experience are all amazed by the sonic improvement this tweak provides, but mostly only comment thereon after eating the crispy bacon byproduct. You can thank me later.
