Introducing the A&ultima SP4000

Astell & Kern, a titan in the portable music player market, is back with a bang! The South Korean audio brand is set to unveil its latest flagship model, the A&ultima SP4000, at the prestigious High End Munich Show next week. This stunning new player promises to continue A&K's legacy of award-winning hi-res audio excellence.

Top-Of-The-Line Features Await

Although pricing details are still under wraps, we can anticipate the SP4000 to reflect the premium standards of its predecessor, the SP3000, which was priced at £799 / $3699 / AU$5499. The A&ultima SP4000 boasts A&K's innovative 'Octa' circuit design, ensuring crystal-clear audio engineering that aims for audio perfection.

Revolutionizing Sound Quality

The SP4000's cutting-edge circuit architecture guarantees precise digital signal delivery to a single DAC, minimizing noise interference while enhancing signal clarity and sound processing. With A&K's 'New Advanced Digital Audio Remaster' technology, users can expect music that sounds more natural, refined, and detail-rich, thanks to its ability to restore lost harmonics.

Impressive Specs

This powerhouse is designed to handle impressive hi-res PCM files up to 32-bit/768kHz, in addition to DSD512. The SP4000 comes with a hefty 256GB of internal storage, expandable via microSD cards supporting up to 1.5TB. For seamless connectivity, it also offers Wi-Fi and DLNA support, USB digital audio output, and a handy USB-C port for charging and data transfer.

Bluetooth Capabilities Like No Other

With support for high-end aptX Adaptive and LDAC Bluetooth codecs, audiophiles can stream 24-bit audio directly to their headphones. Plus, its innovative 'BT Sink' feature allows the SP4000 to act as a wireless DAC when connected to external devices.

All-Day Listening Experience

Enjoy around 10 hours of uninterrupted playback from a single charge, with a full recharge taking only four hours. The SP4000 not only sounds incredible but also looks the part, featuring a robust stainless steel body with a sleek PVD-coated ceramic back and a stylish Perlinger leather case.

In-Ear Monitors to Complement Your Sound

Alongside the SP4000, Astell & Kern is set to launch two new in-ear monitors: the XIO and Luna. The XIO, developed with renowned manufacturer 64 Audio, features a sophisticated 10-driver setup housed in a sleek stainless steel shell. Meanwhile, the Luna is designed in-house and boasts a high-quality micro planar magnetic driver, silver-coated, and copper cables with a balanced plug.
