Matrix Audio TT-1 Digital Audio Transport at Vinyl Sound Buffalo, NY USA

The TT-1 is a compact digital audio transport from Matrix Audio (Xi'an, China), available at Vinyl Sound in Buffalo, New York, USA. Built on the flagship M Series streaming hardware platform with the same powerful processor and MA Player OS, the TT-1 focuses entirely on delivering a low-jitter digital signal to an outboard DAC. Two Accusilicon dual femtosecond clocks dedicated to the 44.1kHz and 48kHz sample-rate families handle timing independently, and five digital outputs include IIS-LVDS via HDMI supporting PCM up to 32-bit / 768kHz and native DSD up to 24.58MHz (DSD512) alongside AES/EBU, Coaxial, Optical, and a dedicated USB DAC port. A DC 12V input accepts an optional external linear power supply as an upgrade path beyond the built-in internal switching supply. Roon Ready certified with Wi-Fi 6, Gigabit Ethernet, an internal NVMe SSD slot, dual USB 3.0 ports, and NAS sharing capability, the TT-1 is a versatile and future-proof digital source for any high-end DAC.

Dual Accusilicon Femtosecond Clocks and Digital Outputs

The TT-1 uses two Accusilicon femtosecond clocks, one assigned exclusively to the 44.1kHz sample-rate family and one to the 48kHz family. Keeping the two sample-rate domains on completely independent clocks eliminates cross-contamination jitter that occurs when a single clock switches between domains, producing a measurably lower phase noise floor at the digital output. All five digital outputs benefit from this dual-clock architecture. Optical Toslink, Coaxial, and AES/EBU handle PCM up to 192kHz and DSD64 via DoP, covering every S/PDIF-capable DAC. The IIS-LVDS output via HDMI transmits true differential I2S at up to 32-bit / 768kHz and native DSD to 24.58MHz (DSD512), bypassing S/PDIF encoding entirely for the lowest-jitter digital link. The USB DAC output supports up to PCM 32-bit / 768kHz and native DSD 24.58MHz, with its actual format ceiling set by the connected DAC.

Upgradeable Power Supply and Storage

The TT-1 ships with a high-quality internal switching power supply covering all operational requirements, and a rear-panel DC 12V input accepts an optional external linear power supply of at least 35W as a non-destructive upgrade. A dedicated linear power supply bypasses the built-in supply, lowering the noise floor of the internal components and improving the transparency and dynamic range of the digital output stage. For local library storage, an M.2 NVMe SSD slot in 2242/2260/2280 form factor holds a silent, high-speed music library. Two USB 3.0 ports accept external drives, and the TT-1 can share its connected storage with other streamers on the local network via NAS functionality. The MA Player OS exposes the internal library over the network via the MA Remote App for iOS and Android, with full NAS, cloud storage, and streaming service integration.

• IIS-LVDS Output Supporting Native DSD512 and PCM 768kHz: Differential I2S via HDMI bypasses S/PDIF encoding for the lowest-jitter digital interface, transmitting 32-bit / 768kHz PCM and native DSD up to 24.58MHz to compatible DACs.
• DC 12V Input for External Linear Power Supply Upgrade: A rear-panel DC input (35W minimum) accepts an optional outboard linear power supply, lowering the noise floor and improving digital output transparency beyond the built-in internal switching supply.
• Wi-Fi 6 and Gigabit Ethernet: Dual-band Wi-Fi 6 (2.4GHz / 5GHz) provides stable wireless streaming for installations where cabling is impractical, alongside Gigabit Ethernet (10/100/1000 Mbps) for wired network connection.
• Roon Ready Certification: Certified Roon endpoint with full hi-res PCM and native DSD support, plus Tidal Connect, Qobuz Connect, Spotify Connect, AirPlay 2, DLNA/UPnP, vTuner, and Radio Paradise.
• Five Digital Outputs for Universal DAC Compatibility: Optical Toslink, Coaxial, AES/EBU, IIS-LVDS (HDMI), and USB DAC outputs cover every digital interface accepted by any modern or legacy DAC.
• Internal NVMe SSD Slot with NAS Sharing: M.2 NVMe SSD (2242/2260/2280) stores a local music library accessible over the network, with the TT-1 functioning as a music server for other streamers via NAS functionality.
• Dual USB 3.0 Ports: Two USB 3.0 ports accept external drives in FAT, FAT32, exFAT, and NTFS formats for additional local storage or CD ripping via an external USB CD drive.
• M Series Streaming Hardware Platform: Runs the same powerful processor and audio-optimized MA Player Linux-based OS as the flagship M Series, controlled via the MA Remote App for iOS and Android.
• Full-Color Front Display: Vibrant full-color display shows album art, track information, sample rate, and bit depth at a glance, with touch-sensitive front controls for source selection and settings.

Frequently Asked Questions

What is the Matrix Audio TT-1?

The Matrix Audio TT-1 is a compact digital audio transport from Matrix Audio (Xi'an, China), built on the M Series streaming hardware platform with no internal DAC. It delivers a low-jitter digital signal through five digital outputs including IIS-LVDS via HDMI for native DSD512 and PCM 768kHz. Two Accusilicon femtosecond clocks handle the 44.1kHz and 48kHz sample-rate families independently, and a DC 12V input accepts an optional external linear power supply. It is Roon Ready certified with Wi-Fi 6, Gigabit Ethernet, an internal NVMe SSD slot, dual USB 3.0 ports, and NAS sharing capability. It is available at Vinyl Sound in Buffalo, New York, USA.

How does the Matrix Audio TT-1 compare to the NT-1 or EverSolo T8?

The Matrix Audio TT-1 sits between the EverSolo T8 and the Matrix Audio NT-1 in the digital transport hierarchy. Compared to the NT-1, the TT-1 uses a switching rather than a 60W toroidal linear power supply, lacks the NT-1's 10MHz external clock input for SC-1 synchronization, and uses a standard Gigabit Ethernet port rather than the NT-1's galvanically isolated SFP fiber optic port. The TT-1 adds Wi-Fi 6 wireless connectivity, which the NT-1 omits for maximum network stability. Compared to the EverSolo T8, the TT-1 provides dual Accusilicon femtosecond clocks for both sample-rate families, an AES/EBU output, an IIS-LVDS output for native DSD512, and a DC input for external linear power supply upgrade.

What is the IIS-LVDS output on the TT-1 and which DACs support it?

The IIS-LVDS output on the Matrix Audio TT-1 transmits a differential I2S signal over a standard HDMI cable, bypassing all S/PDIF encoding and decoding between the transport and the DAC. S/PDIF interfaces encode audio into a serial bitstream that must be decoded and re-clocked at the DAC input, introducing jitter at each interface crossing. IIS-LVDS sends the raw I2S data directly, supporting PCM up to 32-bit / 768kHz and native DSD up to DSD512 at 24.58MHz. DACs that accept IIS-LVDS include models from Matrix Audio, Denafrips, Gustard, SMSL, and other manufacturers that expose an I2S input via HDMI on their rear panels.

Can the Matrix Audio TT-1 be upgraded with an external linear power supply?

Yes. The TT-1's DC 12V input accepts any compatible external linear power supply rated at a minimum of 35W. Connecting an external linear power supply bypasses the built-in internal switching supply, providing cleaner and more stable power to the sensitive internal components including the dual femtosecond clocks, digital processing circuits, and USB DAC output stage. This is a non-destructive upgrade path that requires no modification to the TT-1 and can be reversed at any time. Vinyl Sound Buffalo can advise on compatible external linear power supply options.

What is the difference between the Matrix Audio TT-1 and the NT-1?

The Matrix Audio TT-1 and NT-1 are both pure digital audio transports with no internal DAC, sharing the same M Series streaming hardware platform and MA Player OS. The NT-1 uses a full 60W toroidal linear power supply with multiple LDO regulators across all circuits, a galvanically isolated SFP fiber optic network port, a 10MHz BNC external clock input for SC-1 synchronization, and an isolated USB DAC output with its own dedicated independent linear supply. The TT-1 uses an internal switching supply with a DC upgrade input, standard Gigabit Ethernet and Wi-Fi 6 wireless networking, no external clock input, and a standard USB DAC output without a dedicated isolated supply. Both units share the same five digital outputs and dual femtosecond clock architecture for their respective sample-rate families.

Does the Matrix Audio TT-1 support Roon?

Yes. The TT-1 carries official Roon Ready certification, making it a fully integrated Roon endpoint that appears natively in the Roon interface with no additional configuration. It supports bit-perfect streaming of PCM and native DSD content from a Roon Core over Gigabit Ethernet or Wi-Fi 6, with gapless playback and full metadata and album art display on the front-panel color display.
