Rhea 1a is a digital-to-analog converter combined with a preamplifier function. It is a R2R converter without oversampling (NOS), capable of working in high resolution (Hi-Res). These converters are known for their natural, realistic presentation and non-fatiguing listening.

It is designed for music lovers who prefer to play via streamers or PC. Therefore, it contains a single USB input, which is implemented without compromising on quality, which we would have to do when using multiple digital inputs. Our USB input is galvanically isolated and then the I2S signal is reclocked and thus fed to the converters. This ensures the elimination of ground loops and enormous immunity from interference and jitter, which is very important especially when playing music from a PC or lower quality streamers.

Volume control is implemented by influencing the reference voltage of the converters. This means that no potentiometer is used in the analog signal path, nor is the digital side affected. This has a big impact on the playback quality. So you still play “bit-perfect”. Volume control is either via a motorized rotary knob on the device itself, or via a minimalistic but robust remote control.

Each of the converter channels contains 4 times R2R 24 bit ladder, which brings even greater finesse and detail in the performance compared to using only one ladder.

The maximum output analog signal is greater than the standard line level, and therefore Rhea is able to directly drive power stages that have higher demands on the input signal level. Of course, you do not need to use the preamplifier function if you have your own preamplifier or line amplifier connected after the converter. Simply turn the volume control on Rhea to maximum.

Separate audiograde transformers are used in Rhea for the digital and analog sections. Only linear power supplies are used.

High-purity lead-free audiograde solder with 5% silver and 2% copper is used for soldering the components. This ensures perfect conductivity and durability of electrical connections and even higher transparency and details in the performance of music.

Our products are not mass-produced on a line. Each original piece is assembled component by component by our hands. Each electronic component is tested and measured before installation. After completion, a comprehensive functional testing and parameter measurement follow. Finally, each product is tested in our listening room to make sure that everything is as it should be.
