Turn up the depth, not the distortion. ?
The REL Carbon Special Subwoofer isn’t just about adding bass — it’s about unlocking a whole new layer of realism in your system. From the first note, you’ll notice the difference: deeper extension, faster response, and a level of control that brings music and movies to life in a way most subs simply can’t match.
The Carbon Special isn’t just visually striking — it’s designed to minimize resonance and maximize performance. REL’s expertly tuned driver (12 in. long-throw, carbon fibre cone with inverted carbon fibre centre cap, die cast alloy chassis) paired with a more powerful amplifier (900-watt hybrid amplifier) and increased cabinet volume resulting in breathtaking dynamics, speed, and nuance, delivering commanding bass that feels as refined as it is authoritative.
What really sets this subwoofer apart is its ability to disappear into your system. Instead of sounding like a separate component, it enhances everything around it — expanding the soundstage, adding weight to vocals and instruments, and revealing nuances you didn’t even know were there.
Whether you're spinning vinyl, streaming high-resolution audio, or diving into a full home theater experience, the Carbon Special responds with authority and finesse. Explosive when it needs to be, subtle when it matters most.
For those who demand more from their system, the REL Carbon Special is more than an upgrade — it’s a transformation.

Friends, today we are featuring one of the components that will help us make incredible sound in room 1434 at AXPONA (April 10 – 12) this year. Richard Vandersteen will be joining us as we showcase Vandersteen Audio's L5-ACC Audio Control Center.
The L5-ACC is a meticulously engineered component designed to deliver an unparalleled level of purity and precision in audio reproduction.
At the heart of the Vandersteen Audio Control Center is a state-of-the-art circuit design that prioritizes signal integrity using only five components. Every detail has been listened to, ensuring minimal noise and distortion. The Audio Control Center's ultra-low distortion levels allow it to handle the most demanding audio signals with ease, providing a listening experience that is dynamic, life-like, and transparent.
The Audio Control Center features an intuitive, user-friendly remote. Its finely calibrated volume control, multiple input options, and high-quality components make it a versatile addition to any system.
The Vandersteen L5-ACC is housed in a robust, vibration-resistant chassis that reflects the brand’s commitment to quality and longevity. The bottom center location for the power cord attachment directly couples to the input power circuit. A selection of feet both ground the chassis noise and keep the unit level in use.
This state-of-the-art audio control center contains features not typically found in purist designs, although you may recognize them from vintage designs. These system controls include bass boost or attenuation, treble boost or attenuation, a matrix solution, and mono-to-stereo controls in steps. However, unlike vintage designs, none of these features are in the circuit in Direct Mode. These added controls are “Smoke and Mirrors” meant to improve your listening experience by manipulating recordings that are not normally enjoyable on your system. Vandersteen ensures there will be no sonic difference with the Smoke and Mirrors module because the signal passes through no additional components in the Direct Mode. Of further note, these added features are approved by audiophiles and music lovers, who have experienced them at shows and seminars, adding value to the listening experience. You will find these extra features on the remote, along with a large Direct button. Should you get nervous about adding these extra Smoke and Mirrors, you can quickly return to the minimum component purist Audio Control Center circuit without Smoke and Mirrors by pushing the Direct button to eliminate the extras.
With the Vandersteen Audio Control Center, listeners can expect a remarkable improvement in soundstage depth, detail retrieval, and overall musicality. It’s a must-have for anyone looking to elevate their listening experience to the highest level, offering a sound as close to the original performance as possible.

Friends, we are excited to introduce you to the Aurender NH10: A new category, for them and us: The Audiophile Network Hub. Lest the following inspire TLDR, suffice it to say that our own listening results transcend even the following extraordinary technical prowess. When we remove it from the system, the result is significantly hobbled sound, leading to a profound change in interest in more listening! Or, as one listener put it, "The system sounds broken without it." And, quite alarmingly, phono sounds better too with this little beauty in the chain. Just when you thought it was safe to ignore accessories!

In the world of high-fidelity digital playback, attention to detail extends far beyond DACs and speakers. Audiophiles are recognizing the critical role of network infrastructure in preserving signal integrity. The Aurender NH10 emerges as a purpose-built solution—an audiophile-grade network hub engineered to elevate streaming audio performance to uncompromising levels. Unlike conventional Ethernet switches designed for general data traffic, the Aurender NH10 is specifically tailored for high-resolution audio systems. Its mission is simple yet ambitious: deliver cleaner, more stable, and more precisely timed digital signals to downstream components.

Aurender positions the NH10 as a foundational upgrade—one that enhances the entire playback chain by minimizing noise and timing errors before the signal even reaches your streamer or DAC. At the core of the NH10 lies an ultra-stable OCXO (Oven-Controlled Crystal Oscillator) with a frequency stability of less than 0.005 ppm. This level of precision ensures that all network data is synchronized to a single master clock, dramatically reducing jitter—one of the most persistent challenges in digital audio. Aurender further enhances timing accuracy through FPGA-based clock management, aligning internal processes with extreme precision. For advanced systems, a 10 MHz BNC master clock input allows integration with external reference clocks, pushing performance even further.

Noise in digital audio systems often originates from power supplies and network interference. The NH10 tackles this through multiple design strategies: Pure Linear Power Supply – avoids noisy switching regulators, delivering exceptionally clean power; Advanced Filtering on Ethernet Ports – ensures signal purity across all RJ-45 connections; Optical Isolation via SFP Ports – provides complete electrical separation between devices, eliminating ground noise.

The NH10 reflects Aurender’s commitment to meticulous engineering. Its precision-machined aluminum chassis not only enhances durability but also shields internal components from vibration and electromagnetic interference.

The NH10 is designed to integrate seamlessly into high-end systems: Multiple Gigabit Ethernet ports with specialized filtering; Dual SFP fiber ports for optical networking; support for standard IEEE networking protocols. This flexibility allows users to build hybrid copper/fiber networks optimized for minimal interference.
