Aesthetix Saturn Rhea Tube Phono Preamplifier

Aesthetix Saturn  Rhea Tube Phono Preamplifier

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 is available in two versions: Standard and Signature.

The standard version uses high-grade Rel-Cap polypropylene coupling capacitors. The Signature version uses exotic and expensive coupling capacitors and other critical parts to bring the performance to a higher level. All versions of Rhea can be factory upgraded to Signature.

Reviews & Accolades

"...redefines what's possible at this price level not only sonically, but functionally... transient quickness and speed without etch, a feeling of effortlessness on crescendos, and a deep, layered soundstage..." -Robert Harley

"The metal work, industrial design, interior layout and build quality are exemplary." -Robert Harley
The Absolute Sound Editor's Choice Award (2005-2011): RHEA and RHEA SIGNATURE phono stage

"Rhea's most remarkable accomplishment is to put together an extraordinary combination of sonic performance and useful features at a price that is within reach." -Michael Fremer

Stereophile Class A Recommended Component: RHEA phono stage

"...where the Rhea really shone was dimensionality... senses of heft, depth, and height... a musical flow that is more like a live performance... (Rhea) clearly distinguishes itself as the most accomplished of the three." -Peter Roth

SoundStage!HI-FI (, 2011): RHEA SIGNATURE phono stage comparison with Parasound Halo JC 3 and Ayre P-5xe phono stages

The Absolute Sound Product of the Year (2009): RHEA SIGNATURE phono stage

The Absolute Sound Top Pick (2009): RHEA phono stage

The Absolute Sound Product of the Year (2003): RHEA phono stage
"Ultimately, the essence of the Rheas proved to be their ability to capture the gestalt of the music being played -- a communication of the wholeness of the performance with its emotional impact intact." -Peter Roth (2009): RHEA and RHEA SIGNATURE phono stage.
"...a top choice for smooth, accurate, uncolored, highly detailed sound." -Robert Levi Read review here (2004): RHEA phono stage, read review here

"The Rhea's (performance) was further proof, if any were needed, of the microdynamic magic of fine tubes... Judged by the high standards Jim White set for himself in designing it or considered strictly on its own merits, the Aesthetix Rhea is a runaway success." -Paul Bolin
