TEAC UD-507: Cutting-Edge DAC, Preamp, and Headphone Amplifier

TEAC Corporation has unveiled its newest addition to the audio market, the TEAC UD-507, a redesigned DAC/Preamp/Headphone Amplifier. Part of TEAC’s 500 Series, the UD-507 combines a high-end design idea with a compact kind issue, corresponding to the dimensions of a sheet of A4 paper.

The TEAC UD-507 is supplied with TEAC’s proprietary TRDD5 DAC (TEAC Reference Discrete DAC). This part is designed to reinforce the musicality of audio playback, which ought to present a extra immersive listening expertise. The TRDD5 processes digital enter indicators at 64-bit/512fs utilizing a delta-sigma modulator inside an FPGA, which makes use of a proprietary algorithm. 

This DAC helps as much as 22.5MHz DSD and 32-bit/384kHz PCM playback, and customers can select between multilevel delta-sigma and 1-bit delta-sigma strategies for various sound preferences.

One of the important thing options of the UD-507 is its high-current headphone amplifier. The TEAC-HCLD2 (High Current Line Driver) delivers a most energy output of 1,200mW + 1,200mW (balanced output at 100Ω load), which is corresponding to devoted headphone amplifiers with out DAC performance. The amplifier acquire may be adjusted throughout three settings (Low/Mid/High) to match the sensitivity and impedance of assorted headphones.

The UD-507 additionally incorporates TEAC’s QVCS (Quad Volume Control System), a high-precision analog quantity attenuator. This system, together with a strong high-current line buffer circuit, ensures exact quantity management and strong sign integrity. The twin monaural configuration of the analog output stage, with unbiased D/A converter sections for the left and proper channels, enhances channel separation and stereo imaging.

The TEAC UD-507 provides in depth connectivity choices, together with 5 digital inputs and two analog inputs. Digital inputs comprise USB Type-B (rear), USB Type-C (entrance), coaxial, optical, and Bluetooth. The analog inputs embrace RCA and XLR connections. This big selection of inputs permits the UD-507 to deal with numerous audio sources, from high-resolution digital recordsdata to conventional analog indicators.

For wi-fi audio, the UD-507 helps high-quality codecs corresponding to LDAC, LHDC, and Qualcomm aptX HD, enabling high-resolution audio streaming as much as 24-bit/96kHz. It additionally helps multipoint connectivity, permitting simultaneous connection of two Bluetooth units. Additionally, the unit features a full MQA decoder for all digital inputs besides Bluetooth, making certain high-fidelity playback of MQA-encoded music.

The TEAC UD-507 encompasses a strong chassis with a 2.8mm thick prime plate and a transformer mounted on a floating construction to reduce vibrations. TEAC’s authentic Stressless Feet v2, which creates a spot between the underside plate and the ft, additional controls vibrations that might have an effect on sound high quality. These design parts replicate TEAC’s deal with minimizing exterior interference to take care of audio purity.

The UD-507 consists of superior options corresponding to an asynchronous USB mode, which makes use of the unit’s inside high-precision crystal oscillator to manage knowledge switch, decreasing jitter and making certain correct sound copy. The machine additionally helps a 10MHz exterior clock enter, permitting synchronization with an exterior grasp clock for even greater precision in music copy.

The unit’s up-sampling operate, using RDOT-NEO (Refined Digital Output Technology NEO), can enhance the sampling frequencies of PCM digital audio indicators by 2, 4, or 8 occasions, as much as a most of 384kHz. This function helps enhance the readability and element of digital audio playback.

Key Features:

• Full-stage twin monaural/balanced circuitry.
• Playback: 22.5MHz DSD, 384kHz/32bit PCM, Full MQA.
• Digital inputs USB Type-B, USB Type-C, Coaxial, Optical, Bluetooth.
• Analog inputs: RCA, XLR.
• RDOT-NEO (Refined Digital Output Technology NEO) up-conversion operate (2xFs/4xFs/8xFs),
• Bluetooth audio codecs: SBC, AAC, LDAC and aptX HD.

The TEAC UD-507 shall be obtainable for buy in June 2024 by TEACUSA.com and choose sellers. The MSRP is about at $2,099.99.
