warmest speaker cables you've heard?

wire/cabling is absolutely a tone control, whether we like it or not

questions are more or less, in what sense, and do we know how to employ the effect to the benefit of the system in how it produces the music

Vast majority of cables get the tone control rap because they are dealing with signal resonance primarily by means of tuning them to sound less bad. Always thought they were getting better by eliminating distortions, and that is part of what they do. But what they are left with, they try and tune to sound the way they want. That is why all the different cable brands tend to have the same sonic signature or House Sound. 

Never even dreamed the extent to which they all do this until I tried Townshend F1. Sorry, they are not warm. They are just... right.

If you want the best SCs available, the Silversmith Fideliums.
Believe a 4’ pair are $795.
I replaced $6K cables that are now junk relatively. Warm, I guess so. But if you want to hear everything the SR1as are capable, 30 day trial. You will not return.

I’m curious they are Ribbon Headphones, you’re trying to voice?
You want the mids to be warmer and the highs tamed a bit?

Now you know what a TONE control is used for..

OFC, NOT OCC cable. HIGH stand count # 16-12, with PTFE.

You have to be VERY careful with silver over copper in SC or low strand count cable.

Even a #12 is to big for just headphones. OFC multi wire WEAVE with a high strand count. NO SILVER..  Use red copper ends crimped into place. NO SOLDER. Unless you tin correctly.. or use copper Allen heads.

30.00 usd.. If you want the best for warmth anyway..

Here is a tid bit.. hook up ONLY the left one, not both at the same time.. SEE if you hear the difference and voice the cable the way it sounds the best. In other words reverse the direction, it may help A LOT..

I'd try a contact enhancer too with the copper and let them settle.
In 50 hours, they are going to sound the way they are doing to sound..

Cables are components of a system; amps are also components of a system.

Few people would object to describing a certain amp as warm or cool; so why this knee-jerk negative reaction to this kind of enquiry about cables?
