Hearing is believing?........power cables.......

@randy-11 - people definitely bling out their cars! By performance mods, though, I meant mods that actually increase performance, such as stiffer motor mounts, better air intake assemblies, engine tuning.. I think you caught that differentiation, just making sure.

@williewonka - I started on another helix PC today. It’s for my preamp, it will replace the one I made from braided cat 5 cable. Which, by the way, sounds incredible and has not yet caused my house to burn down. But my amps both have helix cables, so I thought I’d see what one on the pre sounds like. Thanks for sharing all of your hard work. I definitely appreciate it.

The equivalent of a dam is the large capacitors in a linear power supply. If big enough and filtered appropriately then the power cord only needs to be specified properly. If too small then performance will be variable depending on many factors - volume level, power supply levels during the day, power cords and what else happens to be plugged in and turned on.

Like I said, mods that actually increase performance, such as stiffer motor mounts, better air intake assemblies, engine tuning... come at the cost of NVH.

wonka - how do you know that you rely ONLY on your ears to tell you when improvements are observed??

if it is not a blind test, you aren't

Randy-11 - my ears let me know when improvements have been achieved because I hear nuances in the music that I recall from a lifetime playing musical instruments, namely - Piano, drums, electric guitar acoustic guitar, 12 string guitar bass guitar, mandolin harmonica and drums.

When my system responds in a manner that more accurately portrays my memory of those instruments, then I believe it is performing better.

I believe relying on what your memory recalls from actually playing instruments is a far better method to gauge system accuracy and improvements than a blind test.

There are subtleties like...
- the complex harmonics of the piano
-the speed (i.e. dynamics) of percussion instruments
- the complexities produced as the bow hits a stringed instrument
- the sound that a guitar players nails makes as they pluck the strings
- the complex sounds a slide makes on a Dobro guitar
- the spitting sounds that brass players tend to make
- the complex breathing of Oboe and clarinet players
- the mind blowing rangeand complexity of a pipe organ
- and many many more

When a cable allows my system to reproduce those nuances better than another cable then I have heard an improvement - i.e. I trust my ears

As I stated above - I cannot "prove" the science - but then neither can a blind test

Regards

Todd - Thanks for the support, it's nice to know the cables perform well on other systems

 I think you will be pleased with the performance of a Helix power cable on your pre-amp. It should allow it to deliver considerably more details due to improved clarity. At least that is what I have found with source components. Since the signals in a pre-amp are comparatively small, I consider them a "cousin" to a source.

Having a Helix IC between the pre-amp and the main amps would also work wonders - why don't you try one :-)

The Helix cables work together to ensure the neutral side of the entire system stays at zero volts and noise free - hence allowing it to operate to the best of its abilities.

Keep me posted - I would appreciate knowing how things turn out.

Cheers
