alrainbow said Explain your pointplease
Ok now I inderstand. Msb says the same
as Krell. For me I listen and learn from there. The power plants do improve the sound especially in multi wave mode.
But for me my power Amps the improvement is not heard. It’s far more for front end
i use separately powered outlets for Amps. But some live in areas where the power is very polluted as such they may hear improvements I do not
Sorry for the OT but I just wanted to say hi and that I lived in FMB and Sanibel for a few years and attended Edison [if you are a local?]. Just to give you an idea how long ago that was … they were just finishing the bridge to Sanibel as before we had to sail there or take a ferry. Great memories of those carefree beach days.

JimSatala77 said I was an electronics technician in the US Navy for my early year's and I retired from the IBEW local 134 in 2013 with quite a bit of experience dealing with Transient voltages/currents caused by the enormous explosion of the amount of computers and other electronic gadgets we have all become accustomed too in the last 30 year's.Yeah the 'digital power supply' has all kinds of problems with respect to 'dirtying up' our ac supply. Especially in the local environment (ie in close electrical and physical proximity).My point is that if you are noticing a definite SQ improvement in the evening it could be because of less sine wave distortion caused by computer/microprocessor chop of the signal…if not isolated from you’re line voltage by a (isolation)transformer, if you live in a mixed use area where several feeds are coming off 1 xformer.
You can even make a case for solar interference with the power lines on the telephone poles…as the sun heats them up the impedance changes…in other word’s it could be anything or nothing…or even a compressor problem on your A/C unit…I’m not trying to be jerky…I have been doing the same thing with my system trying to find out why sometimes the same tracks played at the same volume sound like it’s live…and other time’s I can tell that it’s Memorex.
But really even the diode bridge powersupplies also add their own ‘noise’ back up stream, where as toasters and lightbulbs are fairly benign.
And yes I too notice the nightly improvement in SQ, but that is only really addressing the ‘peak’ time in SQ.
My primary interest is really, are there benefits, what are they, and what can we do (both easily and with more deliberation and effort) to improve the SQ all the time. Which means the peak times become sublime.
The next ASCC post will deleve into more of the specifics of what I’ve found along these lines.
But the paper after that will draw some conclusions and point to a few of the easier, read sorta low cost possibilites, that are available. And it will also point at what my next few experiments will look into as well.
And I’ve been doing some reading about the old telegraph and early telephone systems.
They were especially concerned with the ground connection.
Just some food for thought for now.

I fingered it out…

Part 2 twenty 2Φ
So far the numbers had increased significantly just in using the 14/3 ‘extension cable’.
But now we’re running the numbers for the dedicated audio feed which uses standard romex solid 12/2 w/grnd, house wiring cable, out of a box, from the hardware store.
ExTech CT70 Audio Run
General CA10 Audio Run
Notice how ALL of the numbers have taken a giant mother may I step up and the reference stubby cable has been equaled or bested by the Shunyata cables in terms of the ASCC readings.
Also notice all the numbers with a yellow background.
This is the only set of tests using all of the cables, mostly because this ac source is what I have my amp and dac plugged into. So to test the other cables on this ac source I just used an unused plug-in at the box. And I really don’t want to move my carefully positioned in-use cables just to test them elsewhere. And as we’ll see it really isn’t necessary because the only other comparable ac source, I call the 1st Splice, isn’t really useable for the audio system due to location, and besides I’m saving that as a surprise for last…
But note that the Vd % listings have dropped from 5% (or more) down to 2-5% using the ‘extension cable’, and are now down to readings in the 1-4% range.
And the ASCC numbers have shot up again, with peak readings near the 1Ka range which is a 50% (or greater in some cases) increase, again.
And of course we now have a range of cables to compare to each other all being fed by my dedicated audio run ac source.
And judging by the amount of yellow background we can see that the majority of the peak readings all belong to 4 cables including the Marigo.
And true to form the 2 testers still have different readings between them.
We saw readings of ≈ 200 or 300 peak amps (depending on the testing device) being able to be delivered to my standard plug in the wall.
The current jumps up to ≈ 500 or 700 peak amps (depending on the testing device), from the ‘extension cable’.
And now we have the Audio Run with ≈1kA peak amps.
So on the post and pillar circuits we get ≈ 30K near instantaneous ‘watts’.
Then using a 14/3 ‘extension cable’ we get ≈ 72K near instantaneous ‘watts’.
And now the romex cable with 1kA x 120 volts we have ≈ 120K near instantaneous ‘watts’.
which is ≈ a 160% increase from the ‘extension cable’,
and a 400% increase from my post and pillar house wiring.
The reason that ‘watts’ is in semi-quotes is they really aren’t ‘real’ watts. Watts is a time domain measurement and in these tests we’re sorta only paying attention to a very small window of time.
This means the instantaneous power delivery has increased 400% by adding a dedicated romex run direct from the panel instead of using the post and pillar house wiring.
But lets look at the numbers for the particular power cables themselves.
This first part is a way of seeing the progression of improvement as the power cables I used became more ’sophisticated’.
And at the two extremes we have the reference Stubby and the AppCord, just like in all the previous tests.
The ASCC numbers from the CA10 run from 500 - 770 which is a ≈54% increase
while the CT70 runs from 0.75 - 1.03kA is a ≈37% increase
And so to consider the total current dumping capability,
Which is (500+770/2) = 635a x 120v ≈ 76K near instantaneous ‘watts’ (CA10)
And (750+1030/2) = 890a x 120v ≈ 106K near instantaneous ‘watts’ (CT70)
You can see why I can’t trust the specific numbers, but the trends continue to hold true and provide useful insights.
So now on to the rest of the cables.
As we move from cable #3 thru to #6 we see a gradual shift towards increasing ASCC numbers and decreasing Vd %’s
This represents a progression of improvement in how I made those DIY based cables using better materials and more advanced treatment options.
The % increases while small are significant in that the SQ change was noticed when the G-4r cable came in to focus. In fact it still is a reference cable for me.
So from .76 to .96Ka = 26% increase (CT70)
And from 550 to 680a = 24% increase (CA10)
Indeed the G-4r cable remains close to the best of the cables numbers in terms of ASCC, Vd%, &Ω measurements, albeit 1/2 step down.
Which leads to the top 3 useful cables, the 2 Shunyata cables and the Marigo cable.
This is where things get a bit murky in terms of trying to use the numbers from these devices to compare individual cables.
Likewise, both the Vd% and the impedance Ω readings between the 2 testing devices, are also somewhat murky.
Overall the trends are clear enough but the ‘accuracy’ of the numbers becomes the fly in the ointment, so to speak.
But having said all of this, we are talking ≈ 1Ka (or slightly less as measured by the CA10) from these ‘best of’ cables. This is roughly 50 times the ‘rated’ current that is protected by a 20amp breaker. Versus ≈ 10 times for the standard (post and pillar) house wiring.
This is a significant increase.
But wait there’s more…

Next up Part 2 twenty - two 2Φ
Very interesting
Electricity is weird.
I’m sorry I haven’t completed this series of investigative posts, but life has intruded smack dab into my research budget and time.
However, if I am successful I’ll be changing the subject of the next paper due to an improvement in my ac power feed from the panel.
I’m hopefull it will yield significant results.
JJ
Ok so this is HUGE.
I’ve been a devotee of hardwiring for decades now.
I recently applied Walker Audio’s SST (Super Silver Treatment) to the fuse contacts, IC’s and ac power cables.
Its hardwiring without the inability to disconnect the leads.
But be warned it can be EXTREMELY messy and disastrous if used improperly.
It is an extremely good conductor and if used on ac power cables and such can short out circuits that aren’t supposed to be, and that would be VERY bad.
But the single greatest impact was to the 4 pin xlr connector to my headphone cable.
Well, until I soldered the ground leads together instead of just using a wire nut at the 1st splice.
Then I soldered the hot and neutral leads there as well…
Um.
Er.
I invite any and all who can perform this mod, to do so…
Smoothness beyond anything I’ve ever heard before, again.
Another HUGE choke point removed…
JJ
Hey JJ
Hope all is well n long time no speak.
Did you perhaps mean Walker Audio io Wilson?
He is indeed a mad tweaker and I even got some spark plugs from him that greatly increased power n torque of my 30hp inboard of my sailboat. It made a huge difference when having to motor especially when manouvering in reverse at a dock.
keep in touch.

Say there Gordon, its been a while…
And yeah, my mistake.
I’ll change it in the post.
I haven’t had my coffee yet… 
And yeah life has thrown some curve balls in my direction, but in the true spirit of making lemonade from lemons I’m aiming to get back on track, sooner rather than later.
