Hand Made SATA Cable for CAT
 
Market access hard drive SATA cable for easy production and reduce costs
Most use a single-core wire, a few are single core copper
As for the single-core silver wire is very rare
And the SATA or USB signal in terms of
Use of multi-core silver wire is the best choice

High frequency transmission line for use of multi-core silver
So I use the special specifications required by sata down the production of Teflon multi-core silver wire
Each transmitter & receiver lines are isolated independent conductors with aluminum foil

The problem is these SATA cables can not made by machine
It only been made by your own hand

Because the performance of the SATA cable to the sound improvement was significant
Can be said the the SATA cable is the most critical components to PC audio
So even if you must spend a lot of time to make a SATA cable
But you will get amazing rewards:)

Great. I would highly appreciate if you explain the making of your cable in more detail with incl photos. What exactly changed in the sound?

I guess maybe the only way this cable may improve sound quality is to shield any noise from the sata cable making its way into the sound card through thin air. I cant try this super cable so i did a control experiment. My music server boots and gets its file from my main computer located 15 meters away. it is conected by ethernet and contains no hard drives or any others for that matter and any sata or ide ports are disabled. I decided to put a hard drive in my music server i ran the sata cable so it was touching the onboard sound card trying to maximise any noise . No diffrence to report so i tried two other sound cards just to be on the safe side one from creatives and another from asus still no change to report. Maybe the OP had a faulty sta cable to begin with..

This is how I do

dismantling SATA cable and Keep the SATA connector

Then you just need a little skill and a lot of patience

In fact, this cable has changed all things


http://www.fotothing.com/photos/3ee/...02b29c_c27.jpg
In this case,
Sata cable provides a higher bandwidth, more dynamic, more clarity and better musical
Before replace this cable,I did not think there is such a big change
It's very hard to belive to me or anyone

main computer gets file from external SSD RAID
Only system SLC SSD replace this SATA cable

Do you have a supplier name and catalogue number for the cable you are using ?
Thanks
Alex

ppastudio 13th December 2011 06:13 PM

Hi Alex,
This internal cable is tailor-made to factory
But I will mail you finished sata cable
If you are interested
Feel free to tell me your address & cable Length
(I have 30cm & 60cm cable)
thanks!

What is the price of your cables?

qusp 14th December 2011 09:02 AM

how do you control the impedance when making by hand? looking at the cable it does not appear to be impedance controlled. it looks like a lot of work, but without machine winding and tensioning for the correct cable lay for characteristic impedance, i feel it will do more harm than good. it also appears as if it would be fairly high in capacitance, the enemy of high speed signalling.

if i have misunderstood and the cable lay is done by machine and only terminated by hand; that would make more sense, but termination also must be exact. i would also be quite interested to test your cable

Honestly, I think it is a marketing post. I do not believe the described level of SQ improvement by a hand-made SATA cable.

marce 14th December 2011 11:45 AM

Never mind impedance matching and control, it is only a high speed digital interface.
What I think happens is that the use of hand made silver cable (which we all know makes the sound brighter) allows the bits representing the high frequency sound to traverse the cable with less problems thus allowing for a much better frequency responce when these high frequecy bits are combined with the low frequecy bits at the dac. it is weel known that while an adequate conductor, copper is a little harsh on the upper frequencies, preffering to transport lower frequecy bits, this is attributed to the duller apearance of copper over silver.
