Transparent network can't be reclibrated for different leghth?

Thank you @oldhvymec on your observation.  I will definitely be interesting to get your views on cables with/wo networks.

I built 2 pairs of the 10 footers with 12/4 soow 99.9 domestic copper, and one pair 17 feet with no inductor, out of  10/2 sjoow 99.9 domestic copper.
They are waiting to be cooked as we speak. If you DIY and go to 8 feet you'll have to add about 5 or 6 more wraps on the inductors. Total between 2.5-2.9 mH. That will work. I don't know how picky your ears are. Mine can't tell the difference between the 17 ft 10/2 or the 10 ft 12/4 before the cooking. LOL The 10 ft. 12/4  did sound pretty good for a plug and play though. After cooking and a little settling, try it again.
I'm a hard core COPPER guy. I just like it....Networks we'll see.

I used copper and gold, 2mm pins, Ys, locking bananas, and two SpeakOn(nickel/silver) to bananas (Bass columns) cables. I've also 
added an option to attenuate, UHF1-? dB, that's for your ears. Things like hard dome, ribbons, running to HOT ect. It's usually a room condition but depends on the ability to correct it without spending $$$$.  A good
6-15.00 USD resistor is pretty darn cheap, in comparison. I'll let you know, if your interested in the results. I just love to tinker...

@gdnrbob you sound like a Audioquest dealer lol

@OP, I would take anything Transparent says with a grain of salt.
If it were me, I would sell the cables and buy a set of Audioquest.

Thanks for the link.  It appears that the inductor change with length.  I was told that the inductors were bury in some glue that minimize resonance so to modify the inductors for different length is essentially building a new network hence not cost effective.
