Morel MPS 2.150 Limited 150W 2-Channel Class A/B Full-Range Amplifier

The MPS Limited amplifiers were developed to mark Morel's 45th anniversary, aimed at audiophiles who prioritise fidelity and power.

HiFi Purity

All connections are gold plated, including chassis-mounted RCA sockets and robust power and speaker wire terminals. The signal path has been meticulously designed throughout, beginning with Burr-Brown OPA2134 op-amps, which give the MPS Limited a natural, detailed sonic character. Low-tolerance surface-mount components and WIMA metallised film capacitors preserve signal integrity through to the amplifier stage. Sanken bi-polar output transistors (MPS 2.150 only) were selected for their linear gain, high output and low distortion. Ultra-low ESR, high-voltage Rubicon capacitors in the power supply and output sections deliver the dynamics and resolution expected of a high-end amplifier.

Optimised for Thermal and Power Efficiency

The compact MPS Limited chassis was optimised using advanced computational analysis to handle the thermal demands of both amplifier topologies while sharing the same chassis dimensions. This keeps power output maximised and stable at any volume level.

Selectable Voltage Rail Power Supply

The MPS 2.150 Limited uses a unique selectable voltage rail design. Because Class A/B amplifiers run hotter than Class D equivalents, this feature lets you match power delivery to speaker impedance and keep the amplifier within its optimal thermal range. Select high-power mode beneath the amplifier for 150W x 2 into a 4 ohm load, or switch to high-current mode for 150W x 2 into 2 ohms. The result is an exceptionally stable platform that makes full use of the amplifier's power potential.

Stackable HiFi Car Amplifiers

The MPS Limited models are fitted with cast aluminium end caps with removable plates, enabling various mounting options including vertical stacking. The optional MPS-STKP stacking plates allow multiple amplifiers to be stacked to minimise floor space consumption. The chassis and stacking plates are designed to maintain maximum thermal efficiency throughout.

Installation Forward

All connections are kept to one side of the amplifier via a single-sided circuit layout, making installation straightforward and tidy. Preamp tuning controls sit under a removable panel on top of the amplifier, alongside auto turn-on selection via remote +12V, signal sensing or DC turn-off sensing.

Simple Elegance

The MPS Limited models are designed with a simple, considered aesthetic, representing a new direction in compact HiFi amplification. Pair this amplifier with Morel speakers — such as the Morel Maximo Ultra 602 MKII — to build a genuinely audiophile-grade car audio system.
