You need to have a capacitance meter, some high end digital mutimeters have them built in.

Cheers George

some really cheap DMMs have 199.9mVac and capacitance readouts built into them.
I have one and gave away another two (to my old school) and all these cheap DMMs were under 5 and work surprisingly well.

I pulled the pair of interconnect and measured with my DDM, and it was read zero.
I took another pair of silver interconnect and again measured with my DDM, it was also read zero too.
I try this silver pair on the system and to my surprise it sounds so good that all highs are presenting pretty neutral and vivid. Now I can compare my lightspeed with my 26 line amp. Will test it for a longer period to comment.

Cannot be zero Albert, are you measuring from center pin to shield at one end, other end open?

Cheers George

No. I measure from one end of center pin to the other end of center pin.
Did I do something wrong ??

Yes, measure from center pin to outside (sheild) at one end, the other end not pluged anywhere.
Cheers George

OK, the one I've been using is 0.157nf/157pf with ofc. The one I'm trying is 0.082nf/82pf with 22 awg pure silver. The 82pf one sounds open, will report after serious listening.
Thanks

Albert

Hi Albert, I recommended to you in the return PM that you should have no more than 1.5mt at <100pf per foot.
The Lightspeed is flat from dc to over 300khz it self.
Then determining factor becomes the interconnect capacitance for the hf rolloff.
And any source coupling capacitors will determin the bass rolloff, none if the source is solid state dc coupled then bass rolloff in not an issue.

Cheers George

George,

The following is my set-up for the moment, direct from cdpro transport RCA out with opamp 110 ohm as of specification. 3 foot interconnect measured total 82pf to 6C33C OTL power amp. Sounds terrific and all spectrum is balance and neutral without any exaggeration. sound stage is very wide and deep, very deep and dark indeed. Will let you know more and thanks for the help.

Albert
