ULTIMATE SOUND MACHINES
The Isis
Isis M75D integrated with volume control, $22,000.
Isis M75P stereo amplifier, $20,000.
| The Isis range of dual channel amplifiers from Analog domain represents the current state of the art in linear amplification technology. It is the result of 15+ years experience in high-performance amplifier circuit design, created to deliver exceptional performance at an attractive price point.The Isis features our recently disclosed proprietary Excalibur circuit. Near-zero distortion, a noise floor well below the human perceptual threshold and the generous power output capability of the Excalibur give the Isis its ability to amplify signals with extreme resolution and control, raising the enjoyment of music to an unprecedented level.The Isis is available in two configurations: an integrated amplifier and a matching 2-channel power amplifier. Both can be configured as monoblock amplifiers, for installations requiring more power in stereo, or for building multi-way systems with frequency splitting, or in multi-channel systems.

The DAC1
DAC 1 $21,000. with volume control.
DAC 1 $20,000. with out volume control.
The DAC1 is available in two versions – with or without volume control. The volume control is implemented as a precision, analog stepped logarithmic attenuator. The output volume is adjusted without affecting signal quality. Having volume control at the source enables the use of power amps, eliminating the need for a preamplifier.We’d like you to relax while listening to your favorite music instead of fumbling around with complicated and often meaningless settings, or worrying about numbers. We’ve done it for you while designing the DAC1. Our goal is to maximize the enjoyment of music from digital sources.

Loudspeakers
The Argus
Brushed black: $49,500. pr
Brushed titanium: $49,500. pr
Black crytal: $60,000. pr
Why another loudspeaker?In early 2017, I started looking for a new reference speaker to use in my development work. I need a true reference speaker that can play any music, at any volume, right up to live levels, when required. There are many loudspeakers out there. Some sound very nice and will do a great job when playing at moderate output levels. How about playback at live sound levels? A few can, most will give up long before that.A suitable, ready-made system simply did not exist. Drawing on my experience in building custom monitoring systems for recording studios, the only solution was to build it myself.The prototype pair came into existence in late 2017. Countless hours went into refining the sound – rearranging the crossover, tweaking component values, fine tuning, listening, measuring, listening again, with the objective to achieve three major goals:uncompromised fidelity at any playback levelhigh efficiency and high power handlingminimal distortion and compressionI can now confidently say the Argus is the reference loudspeaker system I have been longing for.How is the Argus different? In almost everything, actually.The Argus is a Mastering reference class, floor standing, three-way, ported loudspeaker system, intended for reproduction of music with maximum fidelity. It is designed for indoor use. Customized high performance drivers and crossover components enable The Argus to play from whisper-quiet up to live sound levels with unrestricted dynamics, minimal distortion and compression. A flat frequency response, excellent time alignment and close matching of the speakers ensure precise timbre and a realistic spatial presentation.Efficiency, impedance and power handlingNominal efficiency of the Argus is 99dB@2.83V, allowing it to be used even with modest amplifiers. The high power handling capacity provides ample headroom for playback up to live sound levels with minimal distortion and compression. The rated impedance is 4 ohms, dipping to 3.5 ohms in the mid-bass range (150-400Hz) and rising above 4 ohms at all other frequencies.Drivers Dual custom 12” long throw woofers ensure a solid foundation in the low frequencies. The powerful Neodymium magnets, triple demodulation rings, a ventilated motor assembly, a high temperature 3” sandwich voice coil and a very rigid cone make these drivers stand out from the crowd.  The 6” midrange driver has outstanding sound quality due to its extremely low distortion, even at high output levels. Its nominal efficiency is a respectable 103dB/W/1m, thus allowing it to deliver the required output at a reduced power relative to the other drivers with minimal compression.  A precision AMT (Air Motion Transformer) driver renders the high frequencies. Its pleated diaphragm has a much larger area relative to dome or cone drivers, thus providing better coupling with the surrounding air. A significant advantage is the absence of inductance. Near-perfect impulse response and no breakup are the hallmarks of this driver. Its radiation pattern is shaped by a custom waveguide to minimize room effects. |  Finishing optionsThe Argus is available in “Brushed Black” and “Brushed Titanium”.
