Level 1

Straight Wire - Level 1

Significant improvement over standard cables supplied with the device by the manufacturer

the "strips" supplied as standard rarely fulfill the high fidelity requirements that you intended when you purchased the actual device.
For a relatively small investment, the Level 1 cables provide a significant improvement in sound quality compared to the simple red/white plastic cables.
The following features characterize the Level 1

Material	Oxygen-free copper (precise signal transmission)
Insulation	Foam polyethylene/polypropylene insulation (detailed highs)
Shielding	Foil and braid laid tightly and twice (suppression of external interference and noise)
Plug	Gold-plated with silver solder (optimum signal transmission)
Recommendation	up to devices for approx. 500,- €
