Complete inheritance of the superior qualities of Yamaha's Emotional & Dynamic sound.
Dedicated single-ended high-grade integrated amplifier design that faithfully draws out all the intrinsic value of your favourite player or D/A converter
_
The basic design of the power amplifier circuit adopts Yamaha's own, uniquely developed Floating and Balanced Power Amplifier technology.
Adopting output elements with the same polarity on the plus and minus sides of the output stage, and also completely separating the NFB (Negative Feedback) circuit and power supply into total of four plus and minus sides of the left and right channels, results in thoroughly symmetricpush-pull operation of the output stage, Completely floatingthe entire power amplifier circuit from the ground removes any negative impact of minute voltage fluctuations or groundnoise.
Moreover, the output elements are comprised of MOSFETs, which provide a warm and natural sonic character.
The use of MOSFETs, which have the same polarity on the plus and minus sides, further evolves the ideal of a complete symmetrical design, to eliminate sound quality variations due to difference in polaritya major distinguishing characteristic of the Floating and Balanced Power Amplifierresulting in sound with a superior signal-tonoise ratio and superbly well-defined sound field.

Since this device employs a dedicated single ended amplifier, it provides excellent response in amplification of single-ended analogue sound from all kinds of audio sources, such as CD players of D/A convertersand the A-S1100 takes advantage of this in having been carefully fine-tuned for optimum sound quality.
By fully utilising single-ended amplification, the A-S1100 transparently draws out the intrinsic qualities of your favourite audio devices, including those made by other manufacturers.
This amplifier adopts an all-stage fully discrete configuration through all sound circuit stages, using only the most meticulously selected high-precision parts from input to output.
(Applicable during tone control circuit defeat.) The slew-rate of the audio signal has been improved to bring lively and strong response to high musical notes.
Moreover, the tone control circuit lets you switch todefeat state and enable a full discrete configuration that bypasses the op-amp IC of the internal circuit, simply by setting the BASS/TREBLE knobs to their center points.

By strengthening the capacity of the high current route (raising the section area of the cable core wire to about 60% of that of the A-S1000) and by pursuing thorough low impedance design, including forming screwclamped wire connections of major ground points, the A-S1100 boasts excellent speaker drive power with a damping factor of more than 250 (8O, 1kHz).
Along with the large-capacity power source transformer equipped with an EI core, this design delivers bass reproduction that is both strong and uplifting.
We've utilised a high-quality digital volume control specially designed by New Japan Radio Co., Ltd., which consists only of adder-type resistance, removing the impact of slew-rate decline or colouring of the sound, delivering higher purity in the sound, and excellent, fast response to large volume changes and steep transients.
Moreover, the tone controls employ a triple-parallelmethod, minimising the detrimental impact on sound quality seen with straight-line tone controls.
In addition, the bass, treble, and common circuits each utilise simple construction in which the NFB of the ampis not used and the CR elements are simply fixed in a straight line, ensuring exceptionally pure sound reproduction even when tone control is applied and superb response to audio signal transients.
When tone defeat is applied, straight signal flow from only one volume circuit to a discrete configuration buffer amp is realised.

The A-S1100 employs an original EI transformer, carefully customised for optimum compatibility with the chassis.
Combining four large capacity carbon sheath block capacitors delivers an energetic soundeven during high volumethat is possible only with the A-S1100.
Moreover, since the control amp and control system isequipped with twelve shunt type local regulators that prevent deterioration caused by currency fluctuation, a clean and stable power supply is achieved.
The EI transformer is mounted on the chassis using brass washer, restricting internal vibration that would result in noise.

The left-right symmetrical construction with the power supply in the centre and the power amp blocks on the ends achieves greater separation of the left and right channelsnecessary for proper two-channel stereo reproductionand ideal weight balance.
Including fine tuning by a centre frame which extends from the front to the back of the casing and specially made metal legs (selectable from spike or pad), the A-S1100 has superb mechanical rigidity and installation stability that dramatically lessens the impact of external vibrations on sound quality.

The phono amp is comprised of an MC head amp and an equaliser amp, each of which are discretely configured, resulting in a rich sound with pronounced musicality, when playing vinyl records with both MC and MM phono cartridges.

The centre of the main unit features level meters that provide visual enjoyment of the music as well, with therapid and delicate movement of the needles.
The meter is illuminated softly from inside by LED, giving a warm, beautiful lamplight look.
The meter indicators can, along with VU display, be switched to peak display, and can be selected according to your preferences.
The window of the meters has been precision-fit to the panelcompletely flat, with no gapsfor an elegantly beautiful appearance.
RETURNS POLICY
To return goods we have delivered to you, please contact us within 30 days from the date you have received the item. A staff member will then assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be sent for repair, or providing you with a replacement.
Incorrectly Ordered/Change Of Mind:
Refunds are not normally provided where you have simply changed your mind or found the goods cheaper elsewhere. However, if goods have been incorrectly ordered, at our discretion, customers may be credited less a restocking fee.
A change of mind return will only be accepted if:
Please note: For change of mind returns, the shipping cost and method is the customer's responsibility. We will not compensate any returns that are lost or damaged in transit to us. For some change of mind returns, a restocking fee may apply.
Faulty Items
We recommend you immediately inspect any goods that we deliver to you or that you collect from our store to ensure you are completely satisfied with the goods. If any goods arrive damaged, please contact us as soon as possible. We will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund. Replacements and refunds of new products that are damaged on delivery or faulty from new requires a proof of purchase of the product and be returned with all original packaging, accessories and/or manuals included. Refunds will be made via the method of payment you used to make your purchase. If we consider the goods to have breached a consumer guarantee, any shipping costs to return the goods to us will be at our cost and compensated.
Repairs
The product must be returned with proof of purchase, it must not be modified or mistreated in any way and it must not have been serviced elsewhere. Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident. We may provide you with an approximate fee; this may vary due to reasons beyond our control. In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
