ultra low capacitance cables


Please recommend some ultra low capacitance cables . From high dollar to cost no object. I need to re cable and my new preamp suggests these cables. Thank you to all who take a moment to help me.

The spec's on the Bogdan cabling are very misleading due to their construction. The nominal impedance of this cable will vary wildly due to the unequal spacing between the conductors over the length of the cabling. This means that the signal will end up going through an "obstacle course" as the impedance, power transfer and phase related issues vary along the length of the cable. Sean

Arthur: When i make a comment, i'm simply sharing my thoughts and that's all that they should be taken as i.e. my personal opinion. Nothing more, nothing less.

Many of my comments are simply observations made on the technical aspects of the product and the performance that it is capable of delivering. This doesn't necessarily mean that the product that i'm commenting on won't get the job done, is piss poor in every aspect of design quality / construction / performance OR that the product doesn't have some good ideas / redeeming qualities that others might like & enjoy. This is true even if my comments come across as being somewhat negative about the product over-all.

The reason that i say this is that it is hard to make a product that does everything right and keep the price reasonable. By being aware of the specific flaws ( manufacturers call these "design decisions" ) of a product, one may be better able to assess whether it will fit their specific needs and desires. As such, i try to point out the obvious points of contention that i see so that others can be made aware of it too.

In wording things as i do, i probably come across as "harping" on the negative aspects of specific products. Given that i consider "proper design" and consistency of performance to be ordinary goals, i tend to think of these things as being a "standard feature" more than something to tout or rave about. As such, i don't offer as much praise for specific products or design attributes as i should. This is because solid engineering practices and a product that is "working right" is nothing out of the ordinary / worthy of praise to me. I reserve praise for products that are truly outstanding and set themselves above the crowd as an example in multiple different areas.

With that in mind, i've always said that one should buy & use what they like and will enjoy. After all, they are the ones that have to use and listen to their investments, so who better to try and satisfy? Sean

Sean, no offense was taken on my part at all. I was merely stating that Bogdan works in my setup and I was happy with them and the service Ben provides. We're cool as always....
Hi Sean,
I mailed Mark your post and he could'nt find this thread so he asked me to post this response.

Koester's comments:

Hi Sean, your post is an epic. I've done a once through and only wish to
offer one correction, plus one suggestion. The correction I recommend you
make relates to the listing you gave near the end of your post. Re: cables
of differing nominal impedances dramatically influencing power available
from an audio amplifier. You know it doesn't work that way, but the listing
implies you can only get X watts through a cable of Y ohms Zo, given some
fixed amplifier output (Volts i guess). I can elaborate but I'm sure you
will agree without my spelling it out in detail.

The suggestion I have is to always have in the back of your mind, and that
of all readers here, the electrical wavelength of any audio signal of
interest, as the wavelength is of crucial importance in considering the
impact of impedance mismatches.

I'll go with a reminder that audio amps don't have output impedances
matching their anticipated loads or speaker cables, yet RF amps all do match
(try to anyway) the cables they feed.

As i've said before, I concur that low Zo audio speaker cable is a logical
marriage of RF and low frequency design, and support your cause in this
respect. Cheers Mark Koester (RF engineer)
