Introduction
Thank you for purchasing the Wyred 4 Sound mPRE. This compact Pre-
amp/DAC is a very versatile unit that will adapt to many systems for years to come.
Extensive amounts of engineering have been applied to produce remarkable
performance and a noteworthy feature set in a chassis smaller than the average
DAC.
The nature of a Wyred 4 Sound product is able to reproduce your favorite
recording with an abundance of transparency and detail. The internal circuits and
components are carefully selected and designed to reproduce our signature sound.
Nothing is better than having Wyred behind your music!
We understand that there are many products on the market which have
similar features and internal parts. Our implementation is what sets our products at
another level. We design and manufacture in the USA to offer unmatched quality
and value comparable to those produced in regions where manufacturing is much
less costly. Aside from great customer service, build quality and absolute fidelity
remain our greatest strength.
Design and Feature Overview
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
