EverSolo DMP-A8 Streaming DAC / Preamp at Vinyl Sound Buffalo, NY USA The DMP-A8 is a flagship streaming preamplifier from EverSolo (Shenzhen, China), available at Vinyl Sound in Buffalo, NY, USA. Built around the dual-chip AKM AK4191EQ + AK4499EX "Velvet Sound" DAC with a fully balanced R2R ladder volume control, the DMP-A8 combines a high-resolution music streamer, digital-to-analog converter, digital audio player, and preamplifier in a single full-function chassis. It delivers 4.2 V XLR balanced output, 128 dB dynamic range, and THD+N below 0.00009%, with support for PCM up to 32-bit/768 kHz, native DSD512, and full MQA decoding. Winner of the EISA Best Streamer 2024-2025 award and a Stereophile Recommended Component for 2025, the DMP-A8 is available to audiophiles across Western New York at Vinyl Sound, an authorized EverSolo dealer in Buffalo. AKM Dual-Chip DAC, R2R Volume Control, and Dual Power Supply The DMP-A8 centers on AKM's flagship dual-chip DAC architecture, pairing the AK4191EQ delta-sigma modulator with the AK4499EX D/A converter — the top tier of AKM's Velvet Sound lineup. This combination separates the modulation and conversion stages across two dedicated chips, reducing interference between stages and enabling the AK4499EX to operate in its optimal configuration as a pure current-output converter. The analog output stage uses an OPA1612 op-amp and fully balanced circuit topology, delivering a measured XLR dynamic range of 128 dB, crosstalk of -121 dB, and frequency response deviation of only ±0.25 dB from 20 Hz to 20 kHz. Volume control is handled by a relay-based R2R ladder attenuator operating entirely in the analog domain, providing true audiophile-grade attenuation without the bit-depth penalties of digital volume control. A hybrid dual power supply separates the streaming and DAC sections onto independent supply rails, keeping digital noise generated by the streaming processor isolated from the analog output stage. Dual femto-class clocks with extremely low phase noise manage both the 44.1 kHz and 48 kHz clock families for minimized jitter throughout the signal chain. Streaming Platform Support, Roon Ready, and Local Playback The DMP-A8 runs a custom Android-based operating system with native app integration for Tidal, Qobuz, Amazon Music, Apple Music, Deezer, and Spotify, all controlled from the 6-inch Full HD touchscreen or the EverSolo mobile app. Network streaming protocols include Roon Ready, Tidal Connect, Spotify Connect, AirPlay, and DLNA, enabling full integration into any network audio architecture from simple home streaming to reference Roon systems. A dedicated M.2 NVMe SSD slot (sold separately, up to 4 TB) enables the DMP-A8 to function as a self-contained local music server; the EverSolo Music Library application indexes files, retrieves metadata from the cloud, and organizes the library by genre, album, artist, and sample rate. Bluetooth 5.0 with LDAC, aptX HD, aptX LL, aptX, AAC, and SBC codecs enables wireless input. The Qualcomm QCC5125 Bluetooth module handles all BT audio processing. Advanced DSP capabilities include a professional-grade parametric equalizer and six selectable digital filter profiles. Connectivity, Inputs, and Outputs The DMP-A8 is built to serve as a complete digital hub for modern hi-fi systems. Inputs include two SPDIF coaxial, two optical Toslink, one HDMI ARC (eARC), one USB-B for computer audio, two USB-A ports for attached storage, and Ethernet RJ45 alongside 2.4 GHz and 5 GHz dual-band Wi-Fi for network connectivity. Outputs include balanced XLR and single-ended RCA analog, plus digital passthrough via optical, coaxial, and a dedicated IIS output supporting DSD512 and PCM 768 kHz for use with a downstream DAC. The IIS output allows the DMP-A8 to function as a pure transport feeding a reference external DAC while retaining its streaming and library management capabilities. The HDMI ARC input allows the DMP-A8 to receive audio from a TV or AV system and process it through the AKM DAC stage, unifying a two-channel and home theater setup through a single device.
