Product Strengths

• Very clean and noise-free output signal provides a stable soundstage with a very black background at any sound level
• Exceptional bass control and depth delivers a powerful and tight bass response that underpins the overall musical experience
• Offers flexibility with mono, stereo, and bi-amping operating modes, allowing for system upgrades and configuration changes
• Dynamic and fast, reacting instantaneously to the signal it receives and delivering power and subtlety where needed
• Continues the company's aesthetic with the massive perspex front panel covering

Product Considerations

• Speaker binding posts may not be compatible with all types of speaker cable terminations, specifically thicker spades
• The control for the illuminated 'E' on the front is located underneath the amp and may be difficult to access
• May be more 'laid-back', which some may interpret as lacking ultimate transparency or strict neutrality
• Provides only for XLR balanced inputs, though Electrocompaniet can provide appropriate high-quality adaptors for RCA connectors

Comparisons (according to reviewers)

• Brings another level of control and depth to everything, compared to Totaldac Amp 1
• The memorable blackness of bass pinged recognition, compared to Kinki Studio EX-B7 monos

Takeaway: The Electrocompaniet AW 800 M is a powerful and versatile amplifier known for its exceptional bass control, clean output, and dynamic performance. It is a great choice for audiophiles seeking a high-quality listening experience with flexibility for system configuration.

Product Strengths

• Improved high-frequency response melds lower saturation voltage with higher gain
• An upgraded output stage includes 48 power transistors and a 2000VA power supply transformer with nearly 100,000 microfarads of power supply storage capacitance
• A new and far more efficient heatsink design borrowed from the Relentless
• Can remain in class-A for up to the first 100W of their output

Product Considerations

• One of the amps wasn't working properly the entire time
• Measurements may not be stellar, even though the D'Agostino website claims that the Progression's 'distortion, signal/noise ratio, channel separation, and bandwidth measurements have all improved'

Comparisons (according to reviewers)

• The Progression M550 monoblocks replaced the original Progression monos
• Dan D'Agostino said that if he'd listened to the new Progression M550s when he designed the original Momentum monoblocks 10 or 11 years ago, he would have declared the Progression M550s better
• The Progression M550 borrowed from the Momentum
• The M550 borrowed from the Relentless

Takeaway: The Progression M550 monoblocks are a significant advance, with technological improvements resulting in a 'new amplifier' design. The M550s aim to provide both high-powered delivery when needed and sonic accuracy.

Product Strengths

• Pleasing and natural sound at lower listening volumes, reminiscent of tube amplifiers
• Remarkable level of dynamic control over the loudspeaker load, even when pushed to high volumes, resulting in no perceived distortion, sibilance, or unpleasantness
• Warm and engaging sound stage with clarity in imaging and separation of musical elements
• Capable of handling massive dynamic shifts without compromising its panoramic soundstage—showing immense grace under pressure
• Design ensures efficient heat dissipation through convection cooling, ensuring optimal thermal management

Product Considerations

• No functionality to allow for dimming of the internal lighting, which could prove problematic in some light-sensitive home theatre configurations

Comparisons (according to reviewers)

• Vs McIntosh MC1201 monoblocks: Hard to notice a difference in their performance, even at insane listening levels, despite the McIntosh having a much higher power rating

Takeaway: The ML-50 is a visually stunning and technologically advanced amplifier that produces a lovely, subtly warm tonality whilst still sounding crystal clear. It is neutral yet detailed enough to handle any genre of music, making it a worthwhile investment for audiophiles seeking a no-compromise system.

Product Strengths

• Incredibly resolving, with plenty of detail
• Perfectly controlled, 'wide' sound in terms of dynamics and panorama
• A quieter background brings forward a level of detail
• A clearly structured form, with symmetrical divisions and repetitions
• Inspired by the Relentless Epic amplifier series

Product Considerations

• Speaker jacks accept only spades and bare wires, and connecting spades from the top bends the cable significantly
• Components on the rear panel are placed close to each other and not particularly convenient to use

Takeaway: The Momentum S250 MxV amplifier delivers an immersive and detailed listening experience, making it great for those who enjoy actively listening to music. It brings out the best in loudspeakers, offering tremendous dynamics and a wide soundstage.

Product Strengths

• Delivers a complete and unabridged rendition of music, offering a sense of authority and positively influencing the sound
• Presents music as a tightly unified whole, creating a singular event rather than a collection of individual sounds
• Offers beautifully balanced and poised sound across the entire frequency range, from deep bass to detailed highs
• Maintains steady output voltage regardless of changes in load, defying mains input variations, thanks to the Utopik power supply
• The Adaptive Bias Control (ABC) technology establishes and adjusts bias current in real time

Product Considerations

• The high price dictates that all other system components (source, pre-amplification, speakers, supports) need to be of similarly high quality and expense

Takeaway: The Linn Klimax Solo 800 is an uncompromising amplifier that allows one to hear their music in a new light by delivering a complete picture of the sound. It offers exceptional clarity, balance, and control over the music signal.
