Tweaks that work? (yes very subjective topic)


So I wanted to put this out here to the group and I am hoping for a detailed response from @millercarbon.

What tweaks have you done to your system that have worked?

I am looking to fine tune or tweak my system and this is what I have now.

Rega Planar 8 with Dynavector Cartridge 20x2 LO. 
Audiophile Linear PSU SE for the Rega.
Moon by Simaudio 390 Streaming Pre Amp.
Moon by Simaudio 330A Amplifier
Moon by Simaudio 230 HAD
Moon by Simaudio 260D CD Transport.
Raven Audio CeLest Tower Speakers
Raven Audio Soniquil Speaker Cable, Power Cables, XLR Cable.
Transparent Audio 75 Ohm Digital Link 
Furman Elite 15 PF power conditioner.
All are resting on Butcher Block Acoustics Platforms. 

Look forward to the insight.

For me the cheapest tweak was to remove the speaker grills on my Vienna Acoustics Mozart Grand SE’s.  Most speakers sound better with grills removed in my opinion.  Nothing cheaper than free.
I have used and have extra tubes of Total contact also known as perfect path and it works on all cables in your system . It’s not cheap but it works great and if someone wants to buy some I have 5 tubes for sale
Tweaks that worked for me were. 1) dedicated line of 20A on separate phase 2) star wired distribution block. 3) high end receptables and iec connectors Oyaide C004 4) neotech power cables 5) master base under all my equipment 5) audioquest sorbothane pieces (cut to size) under interconnects, low level cabling 6) cable dressing 7) hifi tuning fuses 8) diffusors behind my listening seat 9) JSSG 360 shielding (cable tweak from computer audiophile website) 10) friwo medical smps with ultra low leakage currents for modem and non audiophile equipment 11) linear psu’s for audiophile equipment. 12) hqplayer and fidilizer for htpc 13) star quad geometry for DC cabling. 13) smoke weed 14) play music loud 😁
I'm using a tweak that is definitely not snake oil;  High Fidelity MC-0.5 power conditioner modules. They plug into the duplex receptacles, I'm using three modules. They have added more detail with a smoother presentation, lower noise floor, and holographic sonics.
There is now a MC-0.5 Helix Plus available with increased benefits.


My favorite tweak lately is called the Mystery Tweak. There is one for CDs and one for cassettes. It involves stiffening them and damping them, thereby reducing distortion. I would very much like to say what the Mystery Tweak involves but then it wouldn’t be a mystery any more, would it?
