What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Description
When Wattson Audio visits familiar audio territory, the results are generally anything but familiar. The Madison LE Amplifier is no exception. While the thinking behind and topology of amplifier circuitry has been resolved and refined over many years, the execution and engineering of those circuits, the design and operational choices within them, still offer significant latitude for innovation and optimization.
Compact – Capable - Configurable
When Wattson Audio visits familiar audio territory, the results are generally anything but familiar. The Madison LE Amplifier is no exception. While the thinking behind and topology of amplifier circuitry has been resolved and refined over many years, the execution and engineering of those circuits, the design and operational choices within them, still offer significant latitude for innovation and optimization.
Small can be beautiful
Not surprisingly, the Madison LE Amplifier is more compact than you might expect. The chassis is milled from solid, offering optimum shielding and mechanical characteristics. Locally machined, the petite proportions consume fewer resources in terms of materials and energy, the product leaving a smaller carbon footprint in its wake.
Inside, the amplifier is a carefully balanced mix of the established and the esoteric. The Class AB circuit is a low-feedback design, built around twin transformers and a substantial, linear power supply with custom made capacitors. The audio circuit itself is fully symmetrical and built entirely from discrete components, from input buffer to output. It offers a choice of balanced XLR or single-ended RCA inputs while the output stage employs a single pair of carefully selected, high-power, bi-polar devices per channel.
Switchable operational topology
So far, so conventional – and so...

Reviews
The Emitter II models are considered by real music connoisseurs and uncompromising audiophiles to be the ultimate in amplifier construction. Almost purely by hearsay, a music-addicted and ever-growing fan base has developed worldwide, which has realized its dream of a concert hall in its own home.
Powered by two separate power supplies, the most sophisticated loudspeakers and elaborately constructed dynamic converters are driven to peak sound performance. With an Emitter II Basic, music unfolds in the full dynamic range. From the breath to the slightest rustle on the stage to the power of the full orchestra, the Emitter II Basic reproduces all tones neutrally, powerfully, energetically, with high resolution and unadulterated in the listening room.
Especially at peak levels at concert volume, the playback and spatial imaging remain absolutely stable. Quiet listeners also rave about the noticeable and very pleasant energy in the sound, which makes the music a relaxing and pleasant experience even at low levels.
ASR Audio's Emitter II Exclusive amplifier creates a vast, tube-like soundstage and three-dimensional presentation without tube colorations, while maintaining exceptional transparency and a low noise floor. The brand stands out for its emphasis on measurements and scientific analysis in audio equipment evaluation, often sparking debates between measurement-focused and subjective listening-focused audiophiles.
Expand Details
Product Strengths
- Known for combining the musicality of tube amplifiers with the precision and power of solid-state amplifiers.
- It provides a transparent sound with steel control, without the electronic 'shine' associated with transistor amplifiers.
- Exceptional bass performance, described as deep, explosive, and completely controlled.
- Homogeneous frequency range, offering a very high degree of transparency and control.
- Offers an ability to resolve even the finest musically significant details.
Product Considerations
- Requires a substantial amount of space due to its multi-component design.
- The sound offered might be 'too beautiful' for some listeners, as it is not 'brutal' or 'terse' enough.
- Requires care in using its switches to avoid shutdowns.
- Some reviewers note it was 'dark sounding' on the highs, though it did not lack information.
Comparisons (according to reviewers)
- Compared to Quad ESL loudspeakers, it surpasses the musicality and clarity achieved with many tube amps, rivaling even high-end options like Lamm Industries ML2.2 and Miyajima Laboratory 2010.
- The ASR has better bass and is more transparent than MBL, however, it lacks the grace that MBL offers.
- Compared to Rogue 180W monoblocks, the ASR Emitter II delivers better bass.
- The ASR Emitter II has slightly better bass control than Manley Neoclassic 500, but the Neoclassic 500 has a more marvelous style of fiddling.
- Compared to Edge and Audio Research, the ASR is darker sounding.
Takeaway: The ASR Emitter II Exclusive offers a combination of tube-like warmth and solid-state precision, making the listening experience a very involving one. It provides exceptional control and detail across the entire frequency range, making it a great choice for audiophiles.
