5. The expected price for the SP4000 is over $3,699, with a budget-friendly alternative available in the Mix Wave HiBy R1.
Astell & Kern has revealed its newest top-tier digital audio player, the Anultima SP4000.
Features and Design
The DAP runs on Android and features a 6.1-inch touch screen with a resolution of 2,160 x 1,080. Users can control music playback using a knurled knob that’s designed for high-resolution local and streaming music. Available in black or silver, the player is crafted from 904L stainless steel, the same material used in Rolex watches. It comes in a hand-made Perlinger shrunken calf case.
Storage and Audio Quality
With 256 GB of built-in storage, the player can accommodate microSD cards of up to 1.5 TB, allowing users to store various audio file types, including FLAC, DSD, PCM, and standard MP3 files. Lower-quality audio files go through VSE (virtual sound extender) technology to reclaim lost harmonics, followed by upsampling via DAR (digital audio remaster).
All sound, whether from local files or streaming, is managed by an octa audio circuit design that integrates AK4191EQ digital processors with AK4499EX analog DACs, ensuring a high-quality sound output with minimal noise. The SP4000 is anticipated to either match or surpass the impressive performance metrics of the previous model, the SP3000, which boasted a 130 dB SNR.
Advanced Technology
The Enhanced Signal Alignment (ESA) tech optimizes frequency alignment to lessen time differences that may arise during signal processing, enhancing sound clarity and overall quality. It features an LDO (low dropout) regulator in its power supply to cut down on external electrical noise interference, further improving audio quality. To protect against electromagnetic noise, its internal components are shielded by 99.9% pure copper.
Listeners can enjoy their music wirelessly via standard SBC and higher quality aptX Adaptive and LDAC codecs. The player also accommodates both balanced and non-balanced wired headphones.
The price for the A&K Anultima SP4000 is expected to exceed $3,699, which is the MSRP for the SP3000 available at the A&K store on Amazon.

Samsung Galaxy Buds Core: Is an Affordable TWS Launch Near?
Key Takeaways
1. Samsung is developing a new budget-friendly model of truly wireless earbuds called the Galaxy Buds Core.
2. The Galaxy Buds Core was found on certification websites, suggesting it has a 200mAh battery and a 500mAh charging case.
3. This new model may follow the Galaxy Buds FE and aims to provide affordable options in the market.
4. The expected launch is alongside Samsung’s Galaxy Z Fold 7 and Galaxy Z Flip 7 smartphones in late July.
5. Anticipated features include Active Noise Cancellation (ANC) and over 30 hours of battery life.
Samsung is said to be preparing to introduce a new set of truly wireless earbuds called the Galaxy Buds Core. This model seems to be aimed directly at those who are budget-minded. While the company’s top-tier Buds lineup usually competes in the high-end market, this new TWS could be focused on more affordable options. Here’s what we know so far.
New Galaxy Buds Core TWS in the Works
The Galaxy Buds Core has just come to light after being discovered on two certification websites. Back in April 2025, a supposed Galaxy Buds FE 2 appeared on the BIS database with the SM-R410 model number. However, another entry on the Nemko certification suggests the name Samsung Galaxy Buds Core. This listing also verifies that the earbuds are equipped with a 200mAh battery, whereas the charging case contains a 500mAh battery.
Moreover, the case was identified with the EP-QR410 model number. If this model is indeed called the Galaxy Buds Core, it would directly follow the Galaxy Buds FE. To remember, the Buds FE were a set of budget-friendly truly wireless earbuds positioned below the premium Galaxy Buds 3 series. Recent rumors indicate that the South Korean tech giant might unveil the Galaxy Buds Core alongside its next-generation foldable smartphones.
Anticipated Launch with New Foldables
The Galaxy Z Fold 7 and Galaxy Z Flip 7 are expected to launch in late July. Therefore, we may see new teasers shortly. Like their predecessors, it is anticipated that these new earbuds will feature ANC (Active Noise Cancellation) and offer at least 30 hours or more of battery life as part of their upgrades.
