ISO Regen performance Improvement Cheap!

Is there any value added to putting foamed FEP around a squadcore construction?

[Cornan]

So, today I received these 10 pcs additional beauties! ?

 

 

I immediately started to solder two Vanguard silver plated OCC copper wires to the legs of the Kemet’s. One on each side plus additional electrical tape to prevent any disaster. Looking like this between LPS-1.2 and BluWave Spdif output.

 

 

Hardly surprisingly for me the SQ jumped yet again! This time with a very clear dynamic boost through out the whole frequency register. Even though I listened to Mike Dawe’s album Era I got a very real flashback from the Pink Floyd concert here in Gothenburg many years ago. The same dynamic feeling. The same 4D surround feeling. I feel more of the music inside my body so to speak. Much more than before. More details in the individual instruments. Fibers as I usually call them. Goosebumps ofcourse. Just brilliant! ?

I did’nt know what FEP was before I looked it up. I still don’t know what a squadcore is? ?

Yes its acting as a decoupling capacitor....

Obviously. The question is how bad the downstream regulators need to be before the addition of an external capacitor makes an audible difference. If a £0.15 capacitor provides such a whopping improvement, why didn't the manufacturer include it in the design?

Very interesting! Would you make one more picture – without electrical tape? I want to be sure I understand your idea of adjusting leads to mid parts of Kemet legs.

It's a vehicle the Cable Police ride, armed with their LT3045 regulators, when patrolling for illegal Kenets crossing the border.

I can ofcourse remove it again and take pictures, but the general idea is really very simple. I solder the wires in the dead center of Kemet’s legs after wrapping them around the solid wire legs and pinch them with a plier to make them stay in position and not moving around while soldering them into place. Then I just cover the soldering joints with electrical tape to ensure that the two poles will never touch each other. Finally I bend the the lower part of Kemets legs slightly and unsery them into the screw terminals and tighten the screws firmly. That’s all! Easy! ?

 

Let me know if anything is unclear! ??

*LOL* Yeah, they are probably patrolling this thread very closely for any stupid misstakes. I wonder why I am not already arrested? ?

Because it is a cable issue? I’m just saying! Remember that I use Brooklyn DAC. How bad can their voltage regs be (even if they can be imporoved). Also the LS-HPULNs in SERIES that I am using pre Brooklyn DAC has both a pair of Kemet A750s at their outputs. Still magic! ?

Listening to Marcus Marr & Chat Faker’s album Work. Now this is an album that sounds great in my car. No doubt. However, yesturday it sounded great but today. Today it sound freaking awesome! Killing Jar track is pinch-your-arm-great! Nothing less! ?✌?

FEP is Fluorinated Ethylene Propylene (aka Teflon).

while squarecore might be starquad after Google translate gets thru with it.

Well, sounds pretty much clear...) Thank you!!

I know I know! I was just joking. I understood the squarecore thing instantly but could’nt help myself! ?

Cool! ? Just make sure to turn the Kemet’s in the right direction when you solder them. It can get a bit confusing when using them left and right. ?

Do we have a theory as to why the addition of a Kemet, etc., across the v+ & v -  could have such an effect?

It seems that a polymer aluminum capacitor (e.g., Kemet A750) across DC input may improve SQ by DC buffering/smoothing, shunting AC noise (decoupling and bypassing), and fast transient response to load change. I will try it with my active crossover boards and if that works one might ask why such a simple, cheap and obvious tweak isn't implemented as standard in all audio equipment?

I will surely await your verdict with strawberries and champagne (I’m not a teenager so popcorn and Coke is not an option anymore)! ?

But how many others did? I had to look up FEP and just guessing on the squarecore thing.

Hard to tell, but with a little patience @BigGuy would surely have explained himself. He is a really nice guy (and probably big)! ?

All seriousness aside, I thought this thread needed some comic relief...

You're welcome!

...but what about the foamed teflon?

Exactly. Why it's not used more often is that there is general ignorance in the audio community of how critical it is to attenuate HF garbage, which is like a virulent pest, squeezing its way into the circuitry by every which way it can - you have to shut the door on this stuff by every means at one's disposal.

 

Why? Because it means the difference in the subjective quality exactly as Cornan described - if addressed to a sufficient degree, then convincing sound pops out. Many of the techniques I describe are aimed precisely at getting this aspect of a playback chain in best shape.

At one stage I was looking closely at cable construction, and FEP makes a lot of sense - I bought some specialist cable to experiment with, but never followed through. I would certainly try some, to see if anything was gained.

Oh wow, got a listen in after 24 hours of burn in with my new cable made from 12awg romex. Sounding very very good. And that’s with basic romex wire! Just for the hell of it, I ordered some Neotech solid 12awg teflon coated upocc hook up wire for when the Kemet’s get here. Now, how I’m going to solder and fit Kemet’s and 12g wire I only thought of after the fact. I’ll make it work somehow. Otherwise I have some 14g romex in the basement!

 

I really am thinking gauge and length are big factors here. Of course one thing I could do is lose the Uptone USPCB and use a real usb cable so I could get the mR right next to the LPS-1 and do a direct connection with the 3045 inbetween. Would be way easier with solid wire esp. But then again introducing a usb cable might rise to another set of issues - and expense.

When we have signals above the 50 to 100MHz range, then we can start a serious discussion about cable dielectrics.

Your post seems off-topic here, really just geared towards drawing people into arguments (and that is your M.O.).

 

Why not start your own thread on that very topic elsewhere instead?
