Recommendation
For listeners who appreciate both the vintage musicality of Duelund copper and the resolution and speed of OCC Silver, the Flagship Series offers the most balanced expression of both technologies. It is one of Audiolund’s most comprehensive and technically advanced XLR interconnect designs, developed for audiophiles pursuing the highest levels of system performance.
OPTION: Select Cable Sleeve Color:

1) Default: Gold Foil + Black Stripe on Black Background
- Elegant appearance
- Gold foil finish requires careful handling due to lower wear resistance

2) Gold Foil + Transparent Stripe on White Background
- Premium aesthetic
- Gold foil finish requires careful handling due to lower wear resistance

3) Red Copper + White Stripe on Black Background
- Improved durability
- Better wear resistance compared to gold foil finishes

4) Black + Grey Stripe on White Background
- Clean contemporary appearance
- Excellent wear resistance
Cable Burn-In
Due to their complex multi-core construction and extensive use of solid-core conductors, Audiolund cables require a significant running-in period before achieving optimal performance.
Recommended Burn-In Period
- Most Audiolund cables: 100 to 200 hours
- Flagship Series: 200 to 400 hours
The larger solid-core OCC Silver conductors used in the Flagship Series generally require a longer stabilization period than the parallel multi-strand Duelund Tinned Copper conductors.
