Technical

Preamplifier

The selected input signal is routed via the input and tape monitor relays (all with gold-plated contacts) to the preamplifier input stage (Burr-Brown OPA2604). The “Line Direct” input bypasses the tape monitor relay so that there is only a single switch contact in the signal path and no loading from the tape outputs.

From the input stage the signal passes to the processor-controlled precision volume IC which forms part of the feedback loop of the output amplifier (another Burr-Brown OPA2604). This in turn feeds directly to the two pairs of Line outputs. The result is a fully DC coupled preamp with a very short signal path ensuring maximum signal transparency.

The volume control IC has its own isolated low-noise plus/minus supply regulators in addition to the plus/minus supply regulators for the op-amps. There is even a separate low-noise supply for the relays to keep noise to an absolute minimum.

Power Amplifier

The MXI2080 has two totally separate amplifier modules, each powered from its own dedicated secondary winding on the power transformer. The 3.4kg toroidal power transformer’s two secondary windings each feed directly through ultra-fast rectifiers to 14,000µF of reservoir capacitors – per channel. In addition high-speed film capacitors are wired across the reservoirs to maintain low impedance at high frequencies. This substantial power source connects directly to the amplifier’s output transistors. A separate rectifier system feeds the power regulators for the amplifier’s sensitive input stages. The power transformer is the only component shared by both amplifier channels. The secondary windings and all circuitry thereafter are separate for each channel, ensuring excellent separation and stereo imaging.

The power amplifier uses Myryad’s signature DC5* circuit configuration. The complementary push-pull class A input stage has an exceptionally wide bandwidth, combined with low noise and distortion. From here, the signal is passed on, via the complementary cascode stage, to the main class A gain stage. All of this low power circuitry is powered from low-noise, low-impedance, high isolation regulated power supplies. This ensures that these sensitive circuits are totally unaffected by any noise or distortion present on the high current supplies for the outputs.

The output stage uses the well-proven triple-emitter-follower configuration with two 150W, 230V output transistors per channel. The combination of these output devices and the generously rated power supply results in a peak output current in the region of ±40 amps.

The output signal passes through a high-current muting and protection relay before going on to the gold-plated 5-way binding post speaker terminals. The MXI2080’s amplifier uses specially selected close tolerance main feedback resistor to maintain dynamic linearity.

The DC output voltage is held down to a few millivolts by a DC servo that uses a low-noise high-speed  FET op-amp and high-speed polypropylene film capacitors. There is only a single high-speed coupling capacitor in the signal path – at the amplifier input.

MX3150 Stereo Integrated Amplifier

Introduction

We are proud to announce a launch of the new Myryad MX3150, a successor of the popular MXI2150 amplifier. Delivering same 150 Watts per channel, but with even higher sound quality and better control over speakers, thanks to the newly designed circuit and optimized choice of electronic components. We were also able to gain even more detailed and cleaner sound with a switch to electronic volume control. And to keep up with current market demands, we added in a full digital section, including top quality USB and Bluetooth inputs, for a seamless playback from computer, tablet or smartphone.

The MX3150 features
  • 6 analog inputs, including a short path “Line Direct” input
  • 3 digital inputs, including USB, optical and Bluetooth
  • USB input supports up to PCM 384 Khz/32 bit and DSD128. Optical supports up to 192kHz/24 bit. Bluetooth 5.0, with support of LDAC, aptX, aptX-HD, AAC, SBC and LHDC codecs.
  • Low-noise, low-distortion precision electronic volume control chip PGA-2320, offering range of benefits:
    • Significant improvement from MXI2150’s solid state volume control
    • Better channel separation for wider and deeper sound stage
    • Improved signal-to-noise ratio at low volumes
    • oPrecise and repeatable setting of volume in 0.5dB steps
    • Volume “trim” level can be set individually for each input, to adjust volume levels among all sources.
  • The MX3150’s 150W power amplifier features:
    • oEach power amplifier channel is a totally separate module with its own power transformer (300VA per channel)
    • High current output design, supported by generously rated output transistors (Sanken 2SC3264/2SA1295) and reservoir capacitors (4*10000uF 80V) and a massive toroidal transformer for each channel ensures smooth, effortless delivery of powe
    • MUR8100 fast-recovery diode, offering wider frequency response, better dynamics and improved transparency

Technical
Preamplifier
The selected input signal is routed via the input and tape monitor relays (all with gold-plated contacts) to the preamplifier input stage (TL072). We picked the TL072 after prolonged listening tests, mainly due to its atmospherical and warm sound.

The “Line Direct” input bypasses the tape monitor relay so that there is only a single switch contact in the signal path and no loading from the tape outputs.

From the input stage the signal passes to the electronic volume control chip PGA-2320, which represents a significant improvement from the MXI2150’s solid state volume, providing more details and better sound stage performance. This in turn feeds directly to the two pairs of Line outputs. The result is a fully DC coupled preamp with a very short signal path ensuring maximum signal transparency.

Power Amplifier
The MX3150 has two totally separate amplifier modules, each with its own dedicated power transformer, at 300VA each. The pair of toroidal power transformers feed directly through ultra-fast rectifiers to 40000µF of reservoir capacitors, supplying sufficient power to drive any speakers.

MX 150W power amplifier uses dual-stage differential amplification circuit, with one drive stage and one pull-push amplification stage. Weak current signal passes preamplifier through 2SC2240 and 2A1668 high quality triodes, ensuring amplification of the signal, while retaining the sound quality and all its detail, transparency and musicality..

2SC3286/2SA1668 and 2SC3264/2SA1295 are used as the drive and pull-push stages, assuring reproduction of the large dynamics, without any compression.

Digital Section
We decided to add a digital section into the MX3150, providing each user with a high-quality and practical digital source for their speaker rig. Thoroughly tested and carefully auditioned, to make sure its performance will be equal match to the amplifier section.

Designed around high-performing AKM’s AK4493 DAC and Muse’s 8920 low-pass filter, with a XMOS USB input supporting Hi-Res audio files, up to 32 bit / 384 kHz and DSD128. And with an extra Qualcomm’s CSR8675 Bluetooth 5.0 receiver, that ads comfort of the wireless audio into your speaker rig.
