So do you feel that L R C measurements will tell you anything other than the cables physical properties? Would you need an RFI tunnel Who said that LCR is all you need, and what is an RFI tunnel ? |

@ pre65Running two sets of Klotz MC 5000/MS Audio between amp and Young Dac as well as amp and valve phono stage. Very good. Not heard the SLIC, too spendy for me. |

Who said that LCR is all you need, and what is an RFI tunnel ? Well Dave a great many of the guru's of the internet plus a fair few ex BBC engineers along with just a smattering of the recording industry. I am surprised you are not aware of an rfi tunnel Dave, I mean do you work in some form satellite weather recording domain? The transmission bandwidth's of those high powered sat communications go into the 4+Ghz do they not, microwave arena territory. We had a device in the last place I worked, they were responsible for mobile phone telecommunication masts which required to be fed by various cables which had superior bandwidths. Due to EU legislation all of the devices and feed controllers and data transmission lines had to be certified to various standards and CE testing parameters. A large (20m long) tunnel structure had been constructed in a semi circular formation and was fully screened, inside an array of sensors and antenna's were placed. Using a line impedance stabilization network (LISN) which was connected in continuity to the supplying power to the equipment being tested, also to numerous other dedicated testbeds for that companies specific requirements that were constructed to help in the testing of cables capable of handling larger frequency bandwidths as well as more normal ones. The passive (LISN) networks are designed establish a consistent impedance to allow accurate repeatability of test results. Conducted emissions (those traveling along the equipment / cable) are measured by using an RF connection to a port on the LISN itself. Radiated emissions are measured using an antenna or current-detecting probe connected again to the test subject. You may know an rfi tunnel as a conducted emissions test bed Dave. |

Cool. Glad ya cleared that up.  |

Boy this thread has drifed well of course hasn't it?? These days I just don't care though... I am now treating forums like others do...NOT TOO SERIOUSLY .... |

Yes, I think that cable testing is a fascinating subject but it should be in its own thread now.
Can we keep this one for discussion of the SLIC only, please? Otherwise, large scale pruning will ensue.

So how many here are actually using the SLIC interconnect ??

Just you I reckon, Martin has seen the light! Well as far as I'm concerned I'm the one that's seen the light!!!! I just think Martin prefered what he already had..... as we say each to their own a ? |

So do you feel that L R C measurements will tell you anything other than the cables physical properties? I have a question for you guys:- If you take a piece of wire with a cross sectional area of 1.5mm is multi stranded and exactly 1m long (as practicality allows) it is made of copper and uses a dielectric with a strength of say 1Kva. Then you take another piece of wire with identical L R C characteristics, same cross sectional area, same amount of strands and identical dielectric, same length but a different conductor material. Can you say they would be sound absolutely identical? Should they sound the same Would they sound different, its impossible for them to sound different? Does just measuring the LRC suffice? Dependent on voltage and current flowing, close proximity to sensitive signals? or electron pick up radiated emi /rfi, again depending on signal size and amperes? Would you need an RFI tunnel to really understand what is happening? I only know of two of these outside an education environment Who cares? Does the fact whether the fact that people can hear a difference between wire a and wire b really matter? After all what is happening Gaza / Ukraine / African Ebola outbreak is far more important or going a long way to eradicate cancer. Really puts this subject into perspective. If cables work for you great, if they don't then great also buy some VDH 4mm and job done, but please FFS give up having a mass-debate of this endless repetitive subject. Zathras sees great wisdom here. |

Bev, if you are as happy with these as you say you are then none of this should bother you. If I were you I'd just sit back with a wry smile, a glass of tipple and enjoy them...  |

In chatting with David Brook today, it transpires that he had investigated the SLIC cables I had returned and found that the batch had been mis-wired internally. This certainly would explain the discrepancy between my findings and those of others using the cables. I therefore withdraw all my opinions on them as having been based on faulty product, which seems only fair.

So are you going to give the SLICS another go Martin ?

No Brian, that ship has sailed as I realise that the Yannis cables really suit my system and I've turned my attention elsewhere.

You're going to make an about turn on your review and yet aren't going to have a listen to "CORRECTLY MANUFACTURED" versions? |
