Dear Audio Enthusiast

We're excited to let you know about our new product line scheduled for release next year. This is a complete hardware and software redesign that we've been working on for some time now. We've updated the website with a preview of what's to come. We will keep our mailing list subscribers up-to-date with specs, release dates and pricing, as these become available. Please subscribe to our mailing list here.

You are probably aware that there are significant and ongoing supply chain disruptions that have affected many manufacturers. In our case, components needed for the existing product line are either unobtainable or available only on the grey market at inflated prices and with unknown provenance and quality. Therefore, even though we are currently out of stock, we are no longer planning a new production run of those products. Instead, we are focusing all our resources on development of our next generation of products.

In short, the PreMATE, PreMATE Plus, HDP-4, HDP-5 and HDP-Express II are no longer available. We apologize for any inconvenience this causes, but look forward to sharing the details of our brand new product line with you and taking the state-of-the-art in home audio reproduction to another level.

The DEQX team

Calibrate the speakers first...

DEQX uses real measurements of each individual speaker to generate a precise correction filter that restores the amplitude and timing coherence of the acoustic signal from the speakers. DEQX correction works with regular speakers and multi-amped active speakers.

Only after the individual speakers are calibrated for true high fidelity does DEQX correct for the room's acoustic modes — resonances present in all listening rooms that muddy and confuse the bass region.

After Correction Before Correction

Only after the individual speakers are calibrated for true high fidelity does DEQX correct for the room's acoustic modes – resonances present in all listening rooms that muddy and confuse the bass region.

Audiophile-grade engineering

Every aspect of a DEQX is carefully engineered for optimum audiophile performance. For example: countless design, development, and auditioning iterations were put into the latest A/D convertor circuit and the DAC's I/V (current to voltage) convertor circuits. Over a decade of constant refinement and attention to detail has paid off in superlative performance.

Now add in superb digital coding and algorithms: a −140 dB digital processing noise floor and a precision digital volume control. The end result? A truly transparent component with zero digital artifacts. An "analog" sound for all combinations of input to output: analog to analog, digital to digital, and any combination of the two.

The heart of your system

DEQX preamp processors feature unrivalled functionality and connectivity. In many cases a single DEQX processor will replace multiple boxes, simplifying your system as well as adding functionality and increasing system performance.

Roon is the most engaging, enjoyable way to browse music

Being Roon Ready lets our PreMate Plus and HDP-5 processors transparently discover and connect to Roon – with no network configuration – for bit-perfect delivery of audio.

Together, Roon and DEQX deliver the power, flexibility and performance benefits of networked audio, with the easiest setup and highest reliability available. Learn more at roonlabs.com.

What the reviewers say

Digital Audio Review

The audible improvements are more pronounced than switching up cables, server/streamer, DAC or amplifier. Such is the power of low-latency group delay correction through DSP. Australians say “Maaate”, I say “Bloody marvellous!”.

Positive Feedback

What the DEQX does is create a great presence and separation—in all respects. Instruments become more believable and there. There as in the sense of being there before you… clear and out in an open and 'cleanly' delineated space.

I am unequivocal about my enthusiasm for the speaker-calibration capabilities of the DEQX PreMate. It made my very good speakers undeniably better, smoother and cleaner, and endowed them with a bigger soundstage. It made dense, complicated music easier to resolve, and all music more of a joy to hear.

I now have all of the detail, dynamics, smoothness and spatial attributes I have been searching for with the ability to do room correction and frequency shaping as I wish.  It is a win-win for me.
