I have used a combination of the 4 below mentioned items (all from Audiophonics) to make a small 1,5m speakercable to link Kef eggs and class-d amplifier coupled to PS4. Materials were all easy to handle and of good quality. Happy with the result.
- Heat-shrink tubing 3:1 Ø7.4mm Red (1m)
- Heat-shrink tubing 3:1 Ø7.9mm Black (1m)
- JANTZEN AUDIO SUPRA 5N Speaker Cable OFC PVC 2x2.5mm²
- YARBO SC02 Banana Plug Gold Plated 24k Ø3.5mm (Set x8)
Also used it earlier with good results to retrofit internal cable on speakers (Technics SB-EX3).
