One of the core technologies that make Constellation Audio products so extraordinary is this unique module, which is designed to deliver a more perfect match between the positive- and negative-going halves of the audio signal than conventional balanced preamplifiers can. The result is greater detail, incredible depth and a sound that comes that much closer to the perfectly natural tonality one experiences at a live event.

Because the Line Stage Gain Module employs fully complementary balanced circuitry, with the signal amplified by two “mirror-imaged” preamp circuits, it cancels interference, reduces noise to the vanishing point, and achieves an exceptional slew rate with frequency response out to 200 kilohertz.

In excellent condition, with original box and remote control.

With eight Hybrid DACs, the Select DAC produces an unmatched level of detail. It reproduces the musicality, soundstage, and texture of the original performance, bringing the artist to you. A fully balanced, ultra-high precision, discrete ladder DAC architecture ensures each note tells a story. Additionally, MSB’s robust in-house design enables the finest quality playback of PCM and native DSD, while our low impedance circuitry drives your amplification directly without adding coloration or buffering noise. The end result is a digital experience defying expectations.

This unit comes with the top spec Femto 33 clock, a separate stereo power supply and in custom gold finish. Includes remote control, cables and original flight cases.

Rather than bulking up the Centaur by simply adding more transistors – and losing the delicious subtleties and microdynamics for which smaller, simpler amplifiers are treasured – Constellation Audio’s “dream team” of engineers decided on a different approach. First, we built a superb-sounding 125-watt single-ended amplifier. Then we designed it as a module so that we could achieve any desired power rating by simply adding more modules. The resulting 250-watt-per-channel stereo amplifier sounds exactly like that original 125-watt single-ended amplifier, just twice as powerful.

Like the Hercules, Constellation Audio’s top-of-the-line Reference series amplifier, the Centaur uses a balanced drive design, a unique, fully complementary circuit topology that achieves an essentially perfect balance between the positive and negative halves of an audio signal. Thus, an ideal balance – and the best possible fidelity – is achieved.

The SCM50 ASL (active) are designed to perform at their best in the recording studio or at home with the finest quality hi-fi equipment.

The monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to all performance parameters.

Like the HF, mid and bass drivers, all electronics are designed and manufactured in-house to create a no-compromise active system.

This pair has been sent to the ATC factory in the UK for full upgrading and is the current latest version. We have invoices to prove this.

Powered Subwoofer with 10-inch Subwoofer, 1200 watts

Applying a series of our key technologies, E-Sub powered subwoofers deliver exceptional sound quality, power and value in a wide range of demanding applications

E-Sub drivers employ our exclusive DMA technology to optimize the drivers' motor strength, ensuring linear behaviour over a very long excursion range. Unlike typical steady-state modelling systems, DMA takes into account the dynamic shifts created by current flow and back EMF under real power conditions, with real program material. The payoff offered by DMA optimization is a driver that faithfully tracks its input signal, at all listening levels, leading to superior bass definition and dynamics.

The E-Sub’s active crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass filter feeding the subwoofer's amplifier and a high-pass filtered signal exiting its line outputs. When the on-board crossover is defeated, as is typical in a home theater installation, the line outputs deliver a pass-through, buffered signal identical to its line inputs, easily permitting multiple E-Subs to be interconnected in a ‘daisy-chain' arrangement. Switchable polarity and a fully variable phase control round out the signal processing section. All signal processing is performed in the analog domain, ensuring very low latency in critical applications.

Precision-built in JL Audio's U.S. factory, all E-Sub are individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.

The Model 411 II is mono-functional stereo MC transformer to match with MC cartridges with internal impedance (DCR) of less than 15 ohm. The impedance tolerance is 25 ohms. The transformer is a toroidal design that applies the toroidal winding to 0.05mm thickness of supermalloy, layered ring-core. The core volume has an external diameter of 25mm, internal diameter of 16mm and height of 10mm. The termination of the wire is directly connected to in/out terminal. Therefore, the high efficiency of toroidal transformer realizes extremely low loss structure. It delivers the signal from the cartridge without coloration to the phono- terminal directly.

Model 411II is a modified version of Model 411 and it has 32dB of step-up ratio of approximately 40 times.
