Emitter II / Emitter II Exclusive: High-End Solid State Integrated Dual Mono Power Amplifier

The ASR Emitter II is one of the most advanced solid state integrated dual mono power amplifiers on the market and surpasses many competitor products costing substantially more. It comes in two versions, namely the Emittier II (2x450W / 4ohms) with two separate power supplies with total buffering capacity in excess of 750,000 micro Farads; and the Emitter II Exclusive (2 x 500W / 4ohms) with two separate power supplies as well as an optional battery PSU for the amplifier input circuitry with total buffering capacity in excess of 1,300,000 micro Farads.

The construction of ASR Emitter II is totally different from conventional amplifiers - the Emitter II is technically best described as a power amplifier with high level input selection and volume level adjustment. The Emitter II is equipped with large and powerful high quality Philbert Mantelschnit transformers (4 x 700VA), installed in separate high quality casings --- this keeps the main amp unit from being disturbed by electromagnetic fields and transformer vibration. This is one of the essential preconditions for the calm and relaxing sound-spectrum reproduced by the Emitter II.

The current supply is equipped with an enormous amount of high grade buffering capacitors and ultra-fast rectifiers - this makes the power supply extremely stiff and stable under all listening conditions.

The volume setting features an ultra-precision gain-control relay circuitry, adjustable in 1dB per step with a total range of 75dB. Channel to channel volume level deviation is less than 0.1dB in all setting!

The ASR Emitter II has extremely short signal paths from high-speed input stage to MOSFET-driver and output stage that guarantees crystal clear, precise, spatial and smooth sound characteristics.

The main amplifier case is made from rigid and resonance-free acrylic glass instead of other highly resonant metal material - this acrylic material is audibly more neutral and smooth-sounding than any metal material, especially seeing that it does not counter-react (electrically and magnetically) with the sensitive components inside the amp unit.

All functions of the Emitter II are fully remote controllable - by its smart-looking Corian infrared remote control, or can be operated manually.

The Exclusive version of the ASR Emitters can be (optional at extra cost) equipped with and external Battery Power Supply Unit (PSU) - achieving a true heightened state of organic music reproduction. The Battery PSU supplies the Emitter input-stage section: this is the first gateway to ultra-low signal-to-noise ratio and harmonic distortion. The result is an exceptional homogenous, spatial and relaxing musical performance.

The Emitter II sounds extremely smooth, open and very detailed when compared to other conventional amplifiers, and is also much more stable under extreme listening conditions!

All units are individually hand-crafted in Herborn, Germany, by fully trained employees and may be ordered with various optional extras for enhanced performance; as well as alternative finishes.

Positive Feedback Issue 66 - March/April 2013
"The ASR Emitter II Exclusive Version Blue amplifier is the most musically satisfying amplifier I've ever had the pleasure of listening to - period. In terms of sheer musicality the Emitter II Exclusive Version Blue has bested both the vacuum tube and solid-state amplifiers I have heard. Did that get your attention? The Emitter II Exclusive Version Blue certainly has got my attention! " - Jeff Day

The Absolute Sound - November 2008
"I think this amplifier is revolutionary because, mostly, of the things it doesn`t do, and because of the see-into-and-through transparency that results from its dramatically lowered noise floor (which allowed us to make similar reductions in much of the rest of the audio chain). It has other distinctive attributes, including a sense of "ease" on everything you can throw at it, and maybe to a degree I've never heard from any solid-state product before. It also packs a genuine wallop of those big bass notes that allows you to feel, for example, how tight the skin of a drum is. In other words, it has all the best attributes of the most serious state-of-the-art amplifier contenders." - Harry Pearson

Stereophile - October 2006
"The four-box ASR Emitter II Exclusive proved to be among the most neutral-sounding pieces of audio gear I have ever heard. It bridged the gap between tubes and solid-state as has no other piece of electronics in my experience. It sounded neither tube-like nor transitory. The usual solid-state negatives at the extremes - dryness, etch, edge, overdamped bass, muted, uninvolving - simply didn`t apply to the Emitter II Exclusive. From solo violins and harpsichords to full orchestral climaxes, the amp produced the most natural and realistic sonic pictures I've yet heard in my listening room." - Michael Fremer
