No one actually knows how to lculate what speaker cable they need

For all TELOS 600 owners, here is Mr. Rudolph from Goldmund says:

"Dear Michael,

 what speakers do the customer use with the TELOS 600 ?

 My answers to your questions here under:

 1) we chose this heavy duty Swiss Made silver Coaxial connector in order to perefectly match the speed of Goldmund amplifiers to speakers of various origins . Also for its fastest and most neutral design.

 2) The connectors are not available for sale without the cables which are custom made at Goldmund.

3) What is the maximum gauge of a speaker cable, that this connector can use? : hereafter the info I received from our technician:

--> Please find the specification of the Goldmund Speaker cable for your information:

     - Power Handling : 8.5 kW at 10 MHz.

    - Section : Inner conductor 5.63 mm2. Outer conductor : 2 x 7.4 mm2 crossed shielding.

    - Nominal Impedance : 50 +/- 2 Ohms.

    - Insulation  : > 6 kV.

    - Material : Inner conductor : Cu 99%. Outer conductor : tuned mix Cu 96% & Cu 94%.

    - Weight  : 30 kg / 100 m.

    - Dynamic Minimum Bending Radius : 200 mm.

 Hope it helps.

 Thanks.

 Best Regards.

My recommandation: stay with the binding posts or 

try out how much that custom cable with your spec. would cost at  Goldmund.

b4icu,
Michael, I have another Friend having a Passlab XA 160.8 driving Magico Q5 2.5 meter. Please calculate AWG for his 2.5 meter. Thank you so much. 
I try to buy banana and spade connectors good for 6 or 4 AWG wire locally without any luck. Looks like I need to purchase these connectors from US using a 3 party forwarding house there.

I'm not sure where you're based, but I used chameleon cable on ebay for my spades, and he does spades for lower then 0 gauge.

There's also this guy: https://www.bladeice.com/product/gladen-audio-eco-line-spade-terminals-2-5mm%C2%B2-20mm%C2%B2/ who says he ships to Europe.

Mr.  khiak
For your friend's cable ( Passlab XA 160.8 driving Magico Q5 2.5 meter): 4 AWG.

Mr. kosst_amojan

For your waiting for me to describe this formula, I would kindly advice you don't hold your breath…

Without insulting Mr. John Atkinson, if he would answer this question already, you wouldn't ask for it from me now.

However, if you think that he can help you out, why you are not asking him?

You better do, because this is the last time for me to answer you.

When you (or other) get in a debate to the stage you cannot answer a point, and you go to bring quotes of others, it's a sign that you went short and out of ideas. As so, you most likely bring to the table a quote you do not understand. So the bottom line of such a case is you pull your idol into a debate they never asked for, represented wrongly and badly.
