Smooth as vinyl – pure as digital
We are proud to introduce the Legend 5.2 silverback DS – a fascinating upgrade to an already iconic speaker. With DS (Digital Stream) technology, you’ll experience a sound that is as smooth as vinyl and as pure as digital. You experience deeper bass than ever in present and dynamic soundstage.
A new world of technology
This is a completely different kind of upgrade compared to what you typically see in speakers. Normally, an upgrade might involve a new tweeter or woofer – but nothing as fundamental as a new algorithm in a digitally controlled speaker like this. The algorithm improves everything!
Legend 5.2 silverback DS has been upgraded multiple times since its launch, and DS is only possible because we’ve continuously refined the speaker over the past 7 years – making us a leader in digital loudspeaker technology.
Sounds like nothing else
The DS-sound is exceptionally big with a musical presence and deeper bass than any version of 5.2 silverback. The frequency response is incredibly linear, and the sound adapts beautifully to all music genres and sources – whether it’s streaming, vinyl, CD, or TV.
Streaming High Resolution music from your smartphone to Stereo Hub HT is a special experience – one that might make you question whether physical media still has any advantages at all.

Legend 5.2 silverback DS, the Stereo Hub HT, a remote and a smartphone. All you need for a High resolution streaming experience.
The secret is simplification
DS is not just a technological upgrade – it’s a simplification. The new algorithm is faster, and the sound gets incredible precision, control, and clarity. Combined with the new Stereo Hub HT or Surround Hub, both supporting High Resolution music streaming, you’ll enjoy a sound experience that’s sure to surprise you.
Back to basics – The pure experience
Legend 5.2 silverback DS, paired with Stereo Hub HT, forms a complete and fully integrated wireless music system. High Resolution music files stream directly from the music service’s server all the way to the speaker – without being converted to analog even once. The only conversion happens at the output stage of the speaker’s built-in amplifiers.
There’s no signal manipulation.
No processing.
No compression.
Just the pure experience, exactly as it left the studio.
This uncompromising signal path is only possible because the system’s components are designed to work together – tightly integrated and optimized to deliver sound in its most authentic form.
