Blue Heaven 3 Ethernet Cable is crafted for those who demand precision from streaming sources, and we know Enjoy the Music.com demand the purist, truly lossless digital / streaming music. No compression scams, certainly no mp3, and no psudo-lossless that costs extra to musical artists when for decades we've all been enjoying license-free true lossless FLAC. This cable uses solid core conductors arranged in precision-twisted pairs with individual shielding and a dual-layer braided shield to minimize crosstalk and external noise. Its shielded 8P8C/RJ45 connectors guarantee loss-free transmission, with a starting price of $499.99 per 1 meter.

Blue Heaven 3 USB 2.0 Cable seek to enhances digital connectivity by employing four precision-wound, double-shielded conductors based on the Micro Mono-Filament technology, ensuring clarity, dynamics, and musical detail. It's priced at $319.99 per 1-meter cable.

In addition to the digital cables, we know Enjoy the Music.com fans who love analog audio playback will want to know about the new Nordost tonearm cable. Nordost provided us a special early looks at their forthcoming White Lightning 3 Tonearm Cable. Specifically designed for analog enthusiasts, this cable isolates left and right channels with a twisted pair design, provides dual shielding, and features a dedicated ground wire to minimize hum — ensuring that the authentic tone, texture, and detail of the music shine through. Priced at $649.99 for a 1.25-meter cable, it promises to be a decisive upgrade for discerning audiophiles.

Another highlight here at HIGH END 2025 in Munich is the launch of the QNET7 network switch, a Layer-2 Ethernet switch that has been engineered from the ground up for optimal audio performance. Featuring seven versatile ports — including capabilities for 10/100/1000BASE-T and SFP options — and powered by nine independent ultra-low noise power supplies, the QNET7 minimizes interference and further refines sound staging, 3D imaging, and bass precision. Expected to become the centerpiece of any high-end streaming setup, it will be available later in the year at a suggested retail price of $5,499.99.

To demonstrate the full impact of its innovations, Nordost's German distributor, Audio Reference, will present a complete system demonstration. The setup will include prestigious components such as Wilson Audio WATT/Puppy loudspeakers, a Dan D'Agostino Momentum MxV Integrated Amplifier, a full dCS Rossini system (comprising the Apex player, DAC, and master clock), a VPI Prime turntable, and the Krell K300p phono stage.
