Astell & Kern A&ultima SP1000 Music & Media Player
The Astell & Kern A&ultima SP1000 Digital Music & Media Player is the most recent addition to join the Astell & Kern family of high resolution DAPs.
The SP1000 is the first A&ultima player featuring the latest advancements in AK technology. This one-of-a-kind, high-end powerful high resolution music player features an octa-core CPU for outstanding response and performance.
The High Definition HD5 display comes with the stainless steel and copper housing to create the best viewing experience.
Ultimate Sound Quality
The SP1000 includes the latest AK4497EQ dual-DAC design. Paired with the upgraded CPU, the SP1000 allows for accurate playback of native 32bit/384kHz audio with no compromise on sound quality. The music is played back, bit-for-bit, just as the artists and engineers intended for it to be heard.
The A&ultima SP1000 also supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible.
Get Both High Output and Vivid Sound
Traditionally, as power output is increased, audio has suffered from noise and distortion. Astell & Kern's advanced audio design and signal management technologies used in the A&ultima SP1000 brings more power output with less noise and minimal distortion.
Vivid Sound Creates a Superior Audible Experience
The left and right audio channels include independent DACs to provide a wider soundstage and better stereo separation.
Each AK4497EQ DAC provides rich and vivid audio reproduction, allowing the listener to enjoy the sound as it was meant to be heard.
Great Performance for the Ultimate Experience
The A&ultima SP1000 features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience.
Wider Screen for Vibrant Images
The A&ultima SP1000 features a bezel-less design to maximize screen size.
The high-definition HD5 grade display delivers a vibrant and engaging viewing experience. Song and player information is sharp, colorful and easy to read on the larger, brighter screen.
New Intuitive User Interface for the Ultimate User Experience
Astell & Kern revamped the interface design on the SP1000 to give the user a more music-centric experience from the home screen.
The power button on the volume wheel is located on the side of the SP1000 instead of the top. This allows users to control the volume and turn the LCD screen ON/OFF, all with one simple control.
* When the SP1000 is on the home screen, all functions are centered on the music playback screen.
* The SP1000's user interface provides a simple, minimalist menu design and structure, allowing users to access features and functions quickly and easily.
Faster Charging, Quicker File Transfer
Next generation USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable.
USB 3.0 protocol transfers data twice as fast when compared to other Astell & Kern players.
Charging with a fast charger (at 9V/1.67A) takes only two hours and allows up to 12 hours of continuous playback.
* The maximum 12 hours of continuous play is based on a 24-bit/96 kHz, FLAC file audio file, with the screen off, at 50% volume level, and power output set at low gain playback.
* A fast charger rated 9V/1.67A or a general charger rated 5V/2A are not included.
The SP1000, the first A&ultima player, is like a natural gemstone carefully refined by professionals.
Knowing that sound is reflected from mass, like like is reflected from a surface; Astell & Kern designed the SP1000 like a gemstone with reflective features on its surface.
The crown-patterned volume wheel on the right corner is similar in appearance to a cut gemstone, which reflects light from various angles.
The sophisticated volume wheel on SP1000 not only delivers visual and textual details with precision, but allows convenient, one finger ON/OFF control and fine volume control with the addition of both push and turn features.
The external chassis of the SP1000 is made of rugged stainless steel that resists aging and external shock. The SP1000 is the ultimate music player, crafted in an artistically designed metallic setting.

The UI is snappy and pretty nice, though not bug-free.
Despite my unmitigated love for it, the price is so extreme, and I don't know that it merits it. I mean, I guess it did for me, but I wouldn't readily admit the price to anybody. Note that my review here is for the player combined with its amp, a further $800.
