    Rhea Phono Stage

__________________________________________________________________

.
 

The phono stage—the ultimate combination with the Calypso line stage, dedicating separate power supplies and chassis for line and phono functions. the Rhea features fully balanced differential circuitry with ability to internally balance a single ended input signal, all tube amplification and output, two sets of XLR and two sets of RCA outputs per channel, and a full function remote included.

Rhea is an all-tube phono stage, suitable for moving coil and moving magnet cartridges. It offers high maximum gain at 75 dB, making it ideal for low output cartridges. Rhea broke new ground as the first phono stage with 3 phono inputs, the first with gain and loading settings stored in memory for every input, and the first with full remote control adjustability. Dual-mono audio boards provide superb channel separation and soundstaging. A cartridge demagnetizer is a built-in convenience that can also be operated by remote control. The all-aluminum chassis is designed for rigidity and acoustic inertness, the brushed anodized panels are beautiful too. Rhea has enjoyed worldwide acclaim for its sound quality, build quality, flexibility and ease of use.

• Three RCA inputs.
• Each input has its own gain and loading setting that is saved even when in standby mode or the unit is turned off.
• Zero feedback.
• 40-75dB gain maximum, selectable via front panel or remote control.
• 9 MC loading settings: 75-47,000 ohms, selectable via front panel or remote control.
• Remote control of gain, loading, input switching, mute, and demagnetizer.
• Built-in MC cartridge demagnetizer.
• Two sets of XLR and two sets of RCA outputs per channel.
• All tube amplification and output (10 tubes total).
• Full function remote included.
• Available in black or silver faceplate.

 

RHEA SIGNATURE

The Signature version uses custom-made inter-stage Teflon hybrid coupling capacitors, replacing the polypropylene units, between the 2nd and 3rd, and 3rd and 4th, gain stages (4 total per channel). The change in these capacitors results in higher resolution, extension, less grain and more air. The 2uF coupling capacitor between the 1st and 2nd gain stages is replaced with a 4uF Dynamicap by Peter Moncrief (1 per channel). This change removes grain and provides more openness, while also increasing bass dynamics and slam. The 2uF output coupling capacitors (4 per channel) are also replaced with 4uF Dynamicaps. This change provides more drive, bass extension, resolution and dynamics while also reducing grain. Highly specialized adjustable air-core capacitors, used primarily in the radio-frequency realm, are installed and adjusted to "tweek" each unit to a rigid standard. The five rubber feet are replaced with Harmonic Resolutions Systems' Nimbus Couplers specially made for Aesthetix (Earlier Signature Saturn pieces did not incorporate this, please contact Aesthetix for this free upgrade if you have an earlier Signature piece without the Nimbus Couplers). This change results in a lower noise floor and more air and space. The cost of these specialized parts alone is about 1/4 the manufacturing cost of a brand new unit! Any tubes that can be bettered by our special stock of graded and matched tubes are replaced. Any other improvements needed to make the unit current are installed, including software updates, etc. A new lens with "SIGNATURE" stenciled is installed. Each Signature unit undergoes rigorous test procedures and listening.

JANUS TUBE PREAMPLIFIER



Janus is a full-function all-tube preamplifier with six line level inputs and one phono input. Janus represents the key features of Rhea phono stage and Calypso linestage combined into a single chassis. All tube amplification and output, a fully balanced linestage, discrete switched resistor volume control, versatile single-ended and balanced inputs and outputs, and dual-mono audio boards are all part of Janus. The full function remote controls all preamp and phono functions, including gain, loading, absolute phase and the internal demagnetizer. True to its Saturn Series heritage, the build and sound quality of Janus have won it global praise, including 2010 and 2011 TAS Editor's Choice Awards.

• Fully balanced differential line-level circuitry with ability to internally balance a single ended input signal.
• RCA and XLR provided for each input.
• Discrete resistor volume control with 88 1dB steps.
• Zero feedback.
• Phono input: 40-75dB gain maximum, selectable via front panel or remote control.
• Built-in MC cartridge demagnetizer.
• 9 MC loading settings: 75-47,000 ohms, selectable via front panel or remote control.
• All tube amplification and output (12 tubes total).
• Two sets of XLR and two sets of RCA outputs per channel.
• Bypass mode for home theatre processor throughput.
• Absolute phase, selectable via front panel or remote control.
• Full function remote included.
• Available in black or silver faceplate.

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.

 


NEW  ATLAS STEREO SIGNATURE

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.
