A preamp plays a crucial role in any HiFi system. Its job is rather simple, but developing a component that is able to control levels without adding coloration, distortion, or any other undesirable attribute is a delicate matter. We began by designing a fully balanced circuit from input to output which actively rejects noise and lowers distortion. The noteworthy sonic benefits of the balanced architecture will be evident in both a lower noise floor as well as finer detail. The analog volume control design is very similar in principle to the award winning STP-SE. Additionally, the preamp has been equipped with completely separate right and left channels which begins with the power supplies. As a result of the absolute channel separation and remarkable channel matching, our new mPRE produces holographic imaging that is apparent at all listening levels. The fully balanced, dual mono, dual differential circuit design is unheard of at this price point. Implementing over 80 FET's which are quad-paralleled for lower noise and increased current is only one reason why the mPRE prevails. Input and output stages have been incorporated to preserve sonic integrity throughout the circuit. Because of an extravagant design, you will have the option to pair this preamp with anything from W4S solid state gear to tube equipment with excellent results.
This state-of-the-art preamp has a built-in DAC with three inputs which include Toslink, Coaxial and USB. All digital inputs support 24 bit 192kHz streaming. The ESS Sabre DAC utilizes Hyperstream™ and Jitter Elimination Architecture pg. 3 rendering it immune to jitter. The USB interface is derived from the latest asynchronous XMOS design which is certified USB 2.0 High Speed and Audio Class 2.0 compliant. Consequently, our mPRE requires a quick driver install for PC machines and is driverless for Mac (10.6.4 and above) as well as Linux systems. Incredibly low latency in conjunction with the asynchronous mode communication and ultra precise clocks permits exceptionally high quality digital streaming. A preamp of this caliber and flexibility will efficiently improve your system.
The mPRE is equipped with a total of 3 analog inputs and outputs. Two of the analog inputs are RCA and one of them can be configured as a Home Theater bypass input. The two RCA outputs are the typical variable output type but one of them can be configured as a fixed out. Finishing it off is the balanced (XLR) input and output utilizing high quality Neutrik connectors. Due to the extent of this firstclass design, single ended to balanced conversion is inherent in the design and ensures that all of the independent outputs are active regardless of the selected input. You can be confident that the signal path for your analog sources are highly refined with the mPRE.
On the occasion that you are craving a headphone session, the mPRE has a ¼” headphone jack on the front panel so you can plug right into the high performance headphone amp. Taking advantage of the dual mono design and low noise, the mPRE is nothing short of impressive. All of the benefits the preamp will be even more apparent with the headphone stage. An abundance of dynamic range and power capable of driving headphones down to 16 ohms makes for a true hi fidelity headphone experience.
