Micromega AS-400 200wpc Black Refurb w/phono/digital streaming-10Yr warranty [Expired]

no longer for sale


I have one Factory Reconditioned black 200wpc integrated amp with phono stage and streaming DAC. Excellent reviews & 10 year factory warranty. It has been thoroughly checked by the Micromega distributor, looks great and has all accessories. 

The $4995.00 AS-400 is a very high quality 200 watts/ch integrated amp with 400 watts/ch into 4 ohms. It is very full featured with Remote Control, a nice MM phono stage, 4 analog inputs, full tape loop, processor input, low noise preamplifier, streaming DAC, and preamp/subwoofer output.

The D/A chip is a CS4351 Cirrus followed by discrete pure class A JFET buffers featuring a 1M input impedance producing less than -100 dB distortion from 20 Hz – 20 kHz with low output impedance, a perfect match for the AS-400 specific Air input.

It uses a dual mono amp design with 1000VA transformers, a resistor ladder volume control and nice headphone amplifier. All input switching is done by relays. I have only a few silver new units left.

  • I have a factory refurbished black amp for $1,199.00. Huge savings

  • Quantities are limited. Only 1 left at this deal

           It has the 10 YEAR FACTORY warranty

The AS-400 is Stereophile Class B rated with great sonic reviews. At only $1,199.00 for an amp with warranty, this is $3,800.00 off its original $4995.00 retail, the AS-400 is a killer deal.

The AS-400 also got excellent reviews in The Absolute Sound at its $4995.00 original retail price.

The Absolute Sound review of the AS-400 said:
"Bass control was excellent, something I’ve come to expect from Class D power—the rolling thunder of tympani during Copland’s Fanfare being a prime example, the steady kick of the bass drum during Steve Winwood’s “Higher Love” being another. The Wilson Sophia 3, on the other hand, is a speaker that demands an awful lot from an amplifier. In most instances the Micromega was a model of unflappable consistency and the Sophia sounded fabulous."

"With compact disc, right out of the block the AS-400 had a powerful sense of midrange presence and stability, lively dynamics, and a pleasingly propulsive energy. For me, these attributes created a resolution of vocal nuances that instantly made this amp a top contender in its segment."

"Tonally, the AS-400 was neutral through most octaves with only a slight darkening on top and small losses of air at the frequency extremes. Piano harmonics were rich and full-bodied with a sweetness in the treble that I didn’t typically hear with earlier switching amplifiers. There was a reassuring sense of resonance and harmonic weight throughout."

"The Micromega AS-400 is not just about musicality and performance. It’s equally about the user experience. For many of us the mere mention of music, computers, and wireless networks sets off fire alarms. Micromega, however, has done its homework with the AS-400 and removed any lingering reservations. Now anyone can contemplate a computer-based music collection and step fearlessly into a future of wireless possibilities—or not. The AS-400 happily let’s you have it your way. And believe me, that’s a tough act to follow."

In the Stereophile review Art Dudley summed with:

" the Micromega AS-400 strikes me as a virtually perfect choice for the audio perfectionist who shares space with other listeners—and multiple iPods and/or iMacs. Correct me if I'm wrong, but I don't think anyone else offers this combination of qualities—high output power, a nice preamp with adjustable balance and a healthy number of analog inputs, a phono stage, and instant, out-of-the-box wireless compatibility with the world's most popular music-playback software—for any price, let alone one that seems so reasonable for the design and workmanship on tap. The AS-400 is a unique, and uniquely recommendable, piece of gear."

"This is the component I will be suggesting to my non – hifi friends when they invariably say, “I just want great sound, I don’t want to futz with an elaborate system like yours.  What should I buy?”  Considering how much is under the hood, and the fact that you won’t have to buy a gaggle of cables and power cords, I’m happy to give the Micromega AS-400 one of our Exceptional Value Awards for 2012."

AS-400 benefits from all functionalities from IA-400. AS-400 is fitted with a completely new completely revised AirDream module.

The four main sections, power supply, master clock, digital to analog converter and analog output have been redesigned. Three separate power supplies address each section: Main module, Master clock, D/A analog section. 

Micromega, with over 20 years of experience in amplifier development, is proud to announce AS-400, a very powerful integrated amplifier capable of driving almost all types of speakers, even the most demanding ones. Despite the fact that the unit is integrated, we can consider it as two different units in the same box: the preamplifier section and the power amplifier.

The preamplifier is a very low noise state of the art gain section with extremely low noise power supplies and sophisticated layout to avoid any ground loop. A specific r-core transformer is dedicated to all low levels signals, avoiding cross coupling between the two sections and preventing any disturbance from the mains line to enter the product. Ultra low noise regulators are feeding the preamplifier section to allow very accurate low level resolution. Input switching is done by relays and the input impedance of 100kΩ guarantees that the preamplifier section will not load the different sources connected to it. Volume control is achieved by a digitally controlled resistor ladder with extremely low distortion. The output of the preamplifier section is buffered by j-fet amplifiers and then balanced to avoid ground coupling between the preamplifier section and the power amplifier modules.

The power amplifier section has its own 1kVA toroidal “quiet design” power transformer, followed by ultra fast soft recovery rectifiers and 4x 10,000μF smoothing capacitors in a dual mono configuration. These modules are class D modules with no less that 400W/4Ω output power capacity and 200wpc @ 8 ohms. The choice of class D has been dictated by our quest for reliability, size and sonic quality, together with high efficiency and low temperature operation. The modules are protected for under voltage, over voltage and short circuit. A DC detection circuit prevents any damage to the loudspeakers in case of a dramatic failure occurring to the power modules.

In addition, AS-400 provides a great number of features, some being unique to this kind of amplifiers. A blue VFD display, with 7mm high characters, readable for up to 10m, gives at all time, a clear status of the unit, indicating channel selection and playing level. A balance control is available and has an indication on the front display.

A very high quality MM phono section will please all vinyl record lovers. A sub out, associated with a pass through sub in, allows for different setup when using the AS-400 in a 2.1 system or when using the AS-400 as front amplifier in a multi channel setup. All inputs can be named from a library list stored in the memory of the unit.

Unused inputs can be switched off to optimize access time. A headphone amplifier is available with a front output and its separate volume control setup is stored in the product. A true monitor loop is accessible for users willing to insert an external unit in the signal path.

The case work with its sandblasting finish, available in silver, is superb and the build quality is to the highest standards.
