EX Series M1

The EX Series is tuned to reproduce sound quality with balance mid and smooth extension in both ends, high and low extension. The EX-M1 is fully modular, a dual mono design in a single chassis. Rich in tonal quality, details, dynamic, and high resolution. Silky smooth volume control thanks to the MUSES volume control, of which known for its precise and accurate volume adjustment with precision matched resistors.



Most amplifiers use a potentiometer for volume control. EX-M1 uses an advanced microprocessor-controlled, JRC MUSES72320 2-channel electronic volume, which is optimized for high-end audio and professional audio applications with advanced circuitry and layout. The MUSES72320 performs low noise and low distortion characteristics and with resistance ladder circuit.


The EX-M1 uses extremely high cost 0.2µm gold-plated printed circuit board (PCB). From the perspective of PCBs, it is clear that the designer is well aware of the limitations on the fine contact area of the general circuit board, specifically increasing the soldered area at each solder joint and adding as much shielding as possible.


It uses two 400VA encapsulated transformers, one each for Left and Right channel power supplies. Dual mono power rails does not interfere with each other to improve the channel separation.

You name it. It was engineered to meet the highest quality standard for you.

The power amplification circuitry are mounted directly on a large customs made, gold anodized heat sink. The power stage equipped with two pairs of power EXICON MOSFETs, driven in Class AB.


Two identical power stage modules are arranged on the left and right sides of the chassis, deliver impeccable power for the two channels: 215 watts into 4-8 ohms.

High damping factor unleash the full potential of the sonic performance of the loudspeakers. EX-M1 employes high power rail supplies, delivering fast and high recovery DC supply to the power stage. The ultra high slew rate and DC-coupled (no capacitors in the signal path), yielded exceptionally acoustic excellent - neutral, transparency, details, dynamic and ultra fast transient response.


Vol Control

215Watts RMS into 8Ω

EX-M1 is one of the rare Integrated Amplifier that is able to provide such a good driving capability in its price range. 215W (8Ω), both channel driven, can literally drive anything you throw at it. 


Neutrality and musicality were the goals to achieve. Rich tonal quality, vivid sound imaging, details, high resolution and dynamic. The choice of the components, design, and tuning does just that.


It is the Kinki Studio gears' sound signature.

Broken, chipped or cracked tooth

Rinse your mouth with lukewarm water and apply a cold compress to your face. If the tooth was chipped or broken, bring the tooth fragment wrapped in wet towerl or gauze. Make sure to call us right away

Knocked out tooth

1) For a knocked-out tooth, attempt to carefully place the knocked out tooth back in its socket while holding the tooth by the crown using a clean washcloth, never by the root. If the tooth is dirty, rinse the root and don't scrub it or remove any attached tissue. If reinsertion is not possible, store the tooth in a small container of milk (or alternatively, a cup of water with a pinch of salt) 2) You can walk-in to our office if we are open or go to a 24hr dental service. Having the tooth reimplanted within one hour gives you the best chance of saving the tooth. 3) Take an over-the-counter pain reliever such as Tylenol or Advil but AVOID Aspirin or aspirin substitues which can slow blood clotting.

Bitten tongue or lip

Clean the area with a wet cloth or gauze and place a cold compress to reduce the swelling. If the bleeding continues or if it is excessive, call us or visit an emergency care center


Rinse your mouth with warm salt-water solution (1/2 teaspoon of table salt in 8 ounces of water). Use dental floss to remove any lodged food. If your mouth is swollen, apply a cold compress to the outside of your mouth or cheek. Take over-the-counter pain reliever and use as directed. Contact us soon as possible to schedule an appointment.
Warning: Never put aspirin or any other painkiller against the gums near the aching tooth because it may burn the gum tissue.

Broken Braces Wires

If a wire breaks or sticks out of a bracket or band and is poking your cheek, tongue, or gum, try using the eraser end of a pencil to push the wire into a more comfortable position. If you can't reposition the wire, cover the end with orthodontic wax, a small cotton ball, or piece of gauze until you can get to our dental office. Warning: Never cut the wire. A loose wire can easily be swallowed or inhaled into your lungs.

Loose Brackets and Bands

Temporarily reattach loose braces with a small piece of orthodontic wax. Alternatively, place the wax over the braces to provide a cushion. If the problem is a loose band, save it and call our office to schedule an appointment to have it recemented or replaced (and to have missing spacers replaced).


"Though the Kinki unmistakably belonged to our generic Swiss school, it included that other Swiss, subtle yet distinctive, Nagra aroma. It derives from their signature obsession with tubes even though in much of their recent gear, they don't use valves to get there. Without impact on the noise floor to maintain superb magnification powers, it injects a whiff of textural extra and transient ease. I needn't spell out what that says about the M1's sell price."

"Subjectively speaking, such a result not only involves this scribe more but lively, direct and agile by nature also boils his blood quicker. That’s what the EX-M1 did exactly, it remarkably well morphed my daily speakers into something they aren’t with most electronics and hearing less venting and more OB alike quality from them I’ve found truly impressive."

"How does it sound? I always look for a well-balanced sound, with great detail, but not at the expense of pleasure. Kinki sounds refined, with a huge dynamic with basses that are always precise, extended and never pimpy. The average frequencies are very pleasant and never blatant or aggressive: a clarity also given by the absolute silence that helps to perceive the smallest details."


"The sound is so pure that it’s reoriented the way I listen to music. I no longer listen analytically but for the sheer pleasure. It’s so rewarding and relaxing. Listening to favorites, I’ve noticed that some sound different enough for me to notice that there was some exaggeration or emphasis of certain parts of the frequency with my older set up. Whether it was the house sound that some say certain brands have or just the limits of the design I can’t rightly say. Maybe it’s all the extra circuitry added to accommodate all the extra features I have no use for. No matter. I’m content. Happy as a puppy with two pee pees."


"Result: a smug smile on my face. What EX-M1 brings with respect to Brio-r, all aspects of sound are subsidized. Greater clarity, better separation of instruments, balance more harmonious in the frequency spectra, the lower frequencies richer and less scrambled (which The Black Keys pieces greatly benefit from), a reserve power that responds with ease any solicitation of music ..."
