Aesthetix Saturn Atlas Power Amplifier

Aesthetix Saturn Atlas Power Amplifier

ATLAS amplifiers are capable of driving virtually any high quality speaker. An innovative hybrid design incorporates a bipolar output stage, bipolar driver stage, and vacuum tube input gain stage. They stand alone as the only hybrid amplifiers with zero feedback, essential for maintaining harmonic integrity, air, space and coherence. The Atlas provides your choice of full range or high-pass inputs. This unique built-in filter is ideal for speakers featuring powered woofers, such as Vandersteen, or for audio and home cinema systems using outboard powered sub-woofers. Saturn Series design themes are evidenced in the specialized all-aluminum chassis construction and elaborate power supply design.

• Zero feedback, fully differential amplifier with complementary balanced bridge design for open sound.
• Tube gain stage using one 6SN7 tube per channel provides harmonic accuracy and soundstage layering. This single gain stage provides all of the voltage gain for the entire amplifier.
• Stereo amplifier: 200 watts per channel into 8 ohms; 400 watts per channel into 4 ohms
• Mono amplifier: 300 watts per channel into 8 ohms; 600 watts per channel into 4 ohms.
• Amplifier has a built-in high-pass crossover: 6 dB / octave, 16 settings from 40 Hz to 200 Hz in approximate 10 Hz increments.
• Single-ended and balanced inputs provide extended compatibility.
• Direct input bypasses all crossovers and switching for ultimate purity.
• Bus technology reduces power supply impedance between output devices for more instantaneous current.
• Power supply uses two transformers and three chokes. The high current section uses a dedicated transformer and choke input power supply. The vacuum tube B+ power supply has choke input and is discretely regulated. The result is unequalled clarity and control.
• Cardas patented rhodium-plated binding post with single knob lockdown.
• All aluminum chassis construction assures durability.
• Stainless steel cover for transformers prevents magnetic fields from interacting with sensitive audio circuitry, preserving low level musical nuances.
• RS232 control and trigger for special installation requirements.
• Available in black or silver faceplate.


Atlas Stereo is available in two versions: standard and Signature. The standard version of Atlas Stereo offers all of the features and technologies described above. Atlas Stereo can be factory upgraded to the Signature version.


Atlas Stereo Signature uses the same circuits as the standard Atlas Stereo, but those circuits are implemented with only the highest quality parts available. The standard version uses very high quality Rel-Caps as inter-stage coupling capacitors, while the Signature upgrades these with Peter Moncrief's Stealth capacitors, costing over 10x as much. These provide more detail and information, while maintaining the same award-winning tonal balance. High current output stage power supply capacitance is doubled, increasing bass drive and solidity. Binding post wiring is upgraded to specialized audiophile 14 AWG, which further increases resolution. Another critical refinement is the replacement of all emitter resistors with a specialized metal foil low-inductance type. Atlas Stereo can be factory upgraded to the Signature version.


Atlas Mono is only available in the Signature version, as described above. The mono version dedicates the entire power supply to one channel, increasing space, drive and dimensionality.
