TEAC HA-507

Overview

The TEAC HA-507 is a pure analog headphone amplifier and preamplifier from TEAC's Reference 500 series. Rather than including a built-in DAC, it focuses entirely on the analog signal path, giving you a dedicated, high current amplification stage designed to drive demanding headphones with authority while also serving as a full function stereo preamplifier for a two channel system. It is built for listeners who already own a capable digital source or DAC and want a purist analog partner to extract the most from their headphones.

Engineering highlights include dual monaural construction that keeps the left and right channels fully independent for excellent separation and low crosstalk, along with the TEAC-HCLD high current output buffer that provides the current reserves needed for both high impedance and low sensitivity headphones. Balanced and unbalanced headphone outputs let you connect a wide range of cables and headphones, and the preamplifier outputs allow the HA-507 to feed a power amplifier or active speakers when you step away from headphones.

The HA-507 is ideal for the serious headphone listener who values a clean, uncolored analog character and system flexibility. Pair it with a TEAC digital source such as the UD-701N or NT-505-X and a reference pair of headphones, and it becomes the heart of a dedicated personal listening station.

How the HA-507 Compares

TEAC HA-507 vs Matrix Audio NA-1

The Matrix Audio NA-1 is a compact headphone amplifier aimed at a streamlined desktop setup, emphasizing a small footprint and simple integration. The TEAC HA-507 takes a purist analog approach with dual monaural construction and the TEAC-HCLD output buffer, and it doubles as a full stereo preamplifier for a wider system. Choose the NA-1 for a tidy focused headphone rig, or the HA-507 when you want a reference analog amplifier that can also anchor a two channel system. See the Matrix Audio NA-1.

Recommended Headphones and Source

The HA-507 has no built in DAC, so pair it with a TEAC digital source for the analog input and choose reference headphones that reward its high current output stage.

• TEAC UD-701N A discrete DAC and network player that feeds the HA-507 a clean balanced analog signal, giving you streaming from Roon, TIDAL, Qobuz and Spotify into a purist analog amplifier.
• TEAC NT-505-X A versatile DAC and network streamer with PCM, DSD and MQA support and a 10 MHz clock input, making it an excellent balanced source for the HA-507.
• Audio Technica ATH-ADX5000 An open back reference headphone that thrives on a high current amplifier like the HA-507, delivering airy detail and precise imaging.
• Audio Technica ATH-AWKT A wooden closed back flagship whose rich tone and isolation pair naturally with the dual monaural output of the HA-507 for intimate late night listening.
• Audio Technica ATH-ADX3000 An open back headphone with an even, resolving character that lets the pure analog signal path of the HA-507 shine on both critical and long session listening.

Frequently Asked Questions

Does the HA-507 include a built in DAC?
No. The HA-507 is a pure analog headphone amplifier and preamplifier, so it relies on an external DAC or source for digital playback.

What headphone outputs does it have?
It provides both a balanced XLR headphone output and an unbalanced 6.3 mm output, letting you use a wide range of headphones and cables.

Can the HA-507 be used as a preamplifier?
Yes. It functions as a full stereo preamplifier with balanced and unbalanced line outputs that can feed a power amplifier or active speakers.

What is dual monaural construction?
It means the left and right channels are built as independent circuits, which improves channel separation and lowers crosstalk for a more precise stereo image.

What is the TEAC-HCLD output buffer?
It is a high current low distortion output stage used in TEAC's 500 and 700 series that supplies ample current for driving demanding headphones.

Can it drive high impedance headphones?
Yes. The high current output stage is designed to handle both high impedance and low sensitivity headphones as well as easier loads.

What inputs does the HA-507 have?
It offers balanced XLR and unbalanced RCA line inputs for connecting your DAC or other analog source.

Which TEAC sources pair well with it?
The UD-701N, NT-505-X and other Reference series DACs and network players make excellent balanced sources for the HA-507.

Does it support balanced connection end to end?
Yes. You can feed it a balanced signal from a source and use the balanced headphone output for a fully balanced listening chain.

Is a remote control included?
Yes, the HA-507 ships with a remote control along with a power cable and documentation.

Can I use it with a turntable?
The HA-507 has line level inputs only, so a turntable would need an external phono stage before connecting.

What series does the HA-507 belong to?
It is part of TEAC's Reference 500 series, sharing chassis and engineering philosophy with other 500 series components.

Does it support streaming?
No. Streaming requires a network source such as the TEAC NT-505-X or UD-701N connected to the HA-507's analog input.

Can I connect two sources at once?
Yes. With both balanced XLR and unbalanced RCA line inputs you can connect more than one source and select between them.

Is it suitable for a desktop or a full rack?
Both. Its preamplifier function and reference build make it at home on a desktop headphone station or within a larger two channel system.

How does it compare to a DAC with a built in headphone amp?
A pure analog amplifier like the HA-507 dedicates its full design to amplification and preamp duties, letting you choose your own DAC for maximum flexibility.

What is the warranty?
It carries a one year parts and labor warranty for the original owner, which extends to three years when you register the unit with TEAC USA.

Who makes the HA-507?
TEAC, a Japanese manufacturer founded in 1953, produces the HA-507 as part of its Reference hi-fi line.

Which headphones do you recommend with it?
Reference models such as the Audio Technica ATH-ADX5000, ATH-ADX3000 and ATH-AWKT pair beautifully with its high current output stage.
