TEAC Introduces the AP-507: A Compact Stereo Power Amplifier with Custom NCOREx Technology

full?d=1739467631.jpg

(February 12, 2025) TEAC has announced the launch of the AP-507, the latest addition to its Reference 500 Series. This compact stereo power amplifier, featuring TEAC’s custom-tuned Hypex NCOREx module, is designed for audiophiles wanting high-fidelity sound in a versatile, space-efficient form. Available in black and silver, the AP-507 perfectly complements other 500 Series components.

Despite its small footprint (11.5" W x 3.4" H x 10.75" D), the AP-507 delivers impressive power and flexibility. Designed to function as a standalone stereo amplifier or in more advanced configurations, it supports bi-amping for enhanced speaker performance or BTL (Bridge-Tied Load) mode, where it delivers 350W at 8 ohms for high-power applications. Its compact design also makes it well-suited for integration into AV surround sound systems.

At the core of the AP-507 is TEAC’s customized NCOREx amplifier module, developed in collaboration with Hypex in the Netherlands. This next-generation NCORE technology is engineered to provide a three-dimensional soundstage with superior spatial depth and realism. Enhancing this further is TEAC’s in-house designed dual-mono buffer amplifier, meticulously tuned to optimize clarity and detail, ensuring an immersive and natural listening experience. The amplifier operates silently with a fanless design and carries an automatic power-saving function for efficiency.

Encased in a robust aluminum and steel chassis, the AP-507 is built for durability while incorporating precision engineering to reduce unwanted vibrations. The semi-floating 2.8mm thick aluminum top panel, combined with TEAC’s three-point Stress-Less Isolation Foot system, minimizes resonance and preserves tonal accuracy. The result is a cleaner, more articulate sound with an expansive sense of space.

The amplifier’s power supply features a large toroidal transformer paired with 18,800 μF capacitors per channel, ensuring consistent, high-capacity power delivery. A fully balanced circuit design is implemented at all stages, reducing interference and maintaining signal integrity. Connectivity options include XLR and RCA inputs, allowing for compatibility with a variety of source components. Large screw-type speaker binding posts ensure a secure connection for speaker cables, while a trigger input and pass-through facilitate seamless integration into multi-component setups.

Designed for functionality and aesthetics, the AP-507 features dual-pointer VU meters with a four-step dimmer and two-step sensitivity adjustment. It also exudes a minimalist and refined appearance with its compact form factor and high-quality brushed aluminum finish; it's a design that's sure to complement modern and traditional audio setups alike.

The AP-507 will be available to purchase in spring 2025 from TEACUSA.com and select dealers. The MSRP is $2,199 (USA) and €1,899 (EU). For more details on specifications, availability, and purchasing options, visit TEAC’s official website or contact an authorized dealer.

That is a sweet looking amp... and grab the HA-507 preamp to pair with it... yummy!

One of my favorite experiences was hosting and demoing TEAC's Reference line (with a then brand spanking new Magnapan LRS speakers on loan from a friendly rep firm whose name sadly escapes me) at the Capital Audio Fest 'way back in 2019. Everyone had an absolute blast, me most of all! 😄
 
Back in the day, we used to think Teac was the cheap stuff because we saw it in Radio Shack and Service Merchandise, and it was cheaper than many other brands. Apparently, they've come a long way and now more in the mid-fi to hi-fi arena.

Interestingly, they've had high-end pieces for many years, and have a fascinating and long history of advanced AV technology industry firsts. It would be fun to share my old sales training materials here with everyone. They benefit from a lot of trickle-down engineering from their Esoteric brand.
 
Share it... start a thread and add to it all along... should be interesting. :T

Let me find it first. Was done when I was with Onkyo USA, which doesn't exist anymore,
 
I'm just going to drop this .pdf of the original Onkyo USA* 2019 TEAC Reference Line training deck here. I didn't see a thread for this sort of topic, so if Todd wants to start a new one elsewhere, he can move it on over.

Since most (if not all) here have no idea what I look like, imagine someone more handsome than Mel Gibson in his prime, with the voice of Orson Wells standing in front of you, sweeping you off your feet in that never-ending quest for audio video nirvana. Todd can confirm that everything I say is 99% gospel truth. ;)

*Onkyo USA was, towards the end, distributor only for Onkyo, Integra, Pioneer, and Elite, as well as TEAC and Esoteric. As mentioned elsewhere on AV NIRVANA, I was with Pioneer in home AV marketing and product planning for 20 years, give or take, before being transferred to OUS in 2015. My original job at OUS was international sales trainer (all of the Americas from pole-to-pole, but ended with being part of the two-man design and development team specifically for OIP, and for a time I was handling all the brands---and even dabbled very briefly with Focal, but that's another story. Anyway, in 2020, when OUS sold the OIP distribution rights to Klipsch, I and my fellow developer went over to the exceptionally confusingly organized 11 Trading Company/Premium Audio Company, which is where I remained for the next few years working on next gen OIP products before getting the old heave-ho with around 150 others. 😢

This is a Teac thread, so it should be fine here. :T
 
Great stuff! I love this fact:

"Did you know that the TASCAM 80-8 tape deck was used to record the voices of R2-D2 and C-3PO in the making of the first Star Wars movie in 1977?"

Answer: I didn't! But very cool.

Such a vast amount of detail and technical information. I highly suggest giving it look-thought!
 
Oh... almost forgot. Here's a photo of @Mr.Satyre that was taken circa 2019...

Wow... handsome dude!

Almost as good looking as Todd back in the 80s.
