Speaker Cables, Trying a Few Things

I had been using the Western Electric 14ga tin-plated copper wire. WE actually sourced it from a company in Rhode Island. I decided to try Audio Sensibility's Impact SE speaker cables. They are shielded and cryoed 14ga Ohno Continuous Cast (OCC) Copper. They were $189 CAD, about $140 USD. Steve has a summer 13% off promo and a 30-day trial. They are staying. So, if you are a fan of copper you may want to check 'em out. They are full and harmonically rich. No affiliation just a happy customer.

I also have Dueland wire and Supra wire but the Audio Sensiblity bests them in my rig. 45 amp and Omega 10" Alnico speakers.

Try this one:--

To get you started here is the TQ UB spec.

Cable Specification

Resistance/Metre/Pair 18mΩ
Inductance/Metre/Pair (common mode) 25nH
Capacitance/Metre Between Pairs 2nF
Capacitance/Metre Between Conducting Pairs 4pF
Maximum Continues Current 11Amps
Breakdown Voltage/Metre Between Pairs >2500VAC
Breakdown Voltage/Metre Between Conducting Pairs >5000VAC
Maximum Working Temperature 150°C
Recommended Frequency Range (DC) 10Hz – 250KHz
Recommended Maximum Power Amp Load @ 8Ω 450WRMS
Recommended Maximum Power Amp Load @ 4Ω 950WRMS
Lose in Cable @ 11Amps/Metre 2.7Wmax
Cable Width max 13mm
Cable Thickness max 1.7mm

Conductors are Litz Inductively matched to length each pair.
At 60 Hz, the skin depth of a copper wire is about 8 mm. At 60 kHz, the skin depth of copper is about 0.254 mm. At 6 MHz, the skin depth is about 25.4 µm. Round conductors larger than a few skin depths don't conduct much current near their axis, so that material isn't used effectively. This causes a lose in detail and due to differences in Power/Frequency can cause phase changes producing error in depth of sound. Ordinary twisted conductor do not act like Litz as they conduct on there un-insulated surface to produce a solid conduct, only allowing the possibility to conduct more current as size increases, thus giving a larger diameter and solving the problem with brute force not science or thought. And large diameter wire increases the cost of raw materials and the wastes of money.
Please also note as the diameter increases and the gap stay relatively small the capacitance also is increasing reducing the bandwidth and having the opposite response to your need, not counting the fact of the wasted power to charge and discharge this capacitor as the amplifier swing its output voltage following the audio, this often cause another undesirable effect the amplifier become unstable and burnout in the worst case scenario.
