Limited to 100 units, the price is ¥130,000, which is a low price among the company's products.


We will handle the items at our store, but since the amount is for donation purposes and there is almost no profit margin, AMP-KUMAMOTO will accept payment only by bank transfer.


Please note that if production begins after the final number of reservations is less than 100 units, additional charges may be incurred.


If you are interested, please feel free to contact us.

In order to reduce the price, we purposely did not use the expensive SATRI-IC and covered the latest SATRI circuits.We also designed a new bias circuit that is not affected by fluctuations in the power supply voltage to stabilize the bias current to the utmost, and we also revised the output stage to separate the signal current and bias current.
The specifications are as follows.
○ AMP-KUMAMOTO's input 1 is the RCA connector on the back, and input 2 is the mini jack on the front. By connecting the mini jack to your smartphone, you can use this unit as a music player for your smartphone, etc.
○ The speaker supports 4Ω to 8Ω. At 4Ω, you can get a maximum output of 20W. It can also be used as a headphone amplifier and has a mini jack. The maximum output is 18W + 18W (8Ω), which is a little low, but I think the specs are sufficient for everyday music listening.
○ Weight is approximately 5 kg. It is portable. The case is made of aluminum and was designed by artist Tomoko Katayama (Audio Dojo Master) with a Higo inlay motif.

Due to the number of lots, if the final number of reservations is less than 100 and we start production, the product price will inevitably be revised.

Also, at the time when the sale of AMP-KUMAMOTO ends, we plan to announce the commercial version SCA-7500. (According to the current plan, SCA-7500 JAPAN is expected to be about 1.3 times the price of AMP-KUMAMOTO, and SCA-7500 KOREA about 1.6 times the price.) The basic circuit is the same, but the accuracy and the components used are slightly different, and detailed materials will be announced at a later date.

[Mr. Kazuma Nishino's First Impression of AMP-KUMAMOTO]

Mr. Nagai,
So, I immediately listened to the new amp. Hmm, it sounds better than anything before.
The sound is clearly different from the previous SATRI. It's really good.
Last night, I connected it to the Old Sterling on the second floor and listened to various things. The focus is so precise, and yet so beautiful... there may be other amps that emphasize energy or power, but the beauty of the sound is wonderful. Listening does not feel tiring at all, and it feels like both my head and body are relaxed.
With JBL horns, it plays according to JBL characteristics, and with Sterling, it fully brings out the charm of this speaker...
I am currently playing the new amplifier in the office. In the afternoon, I will bring the equipment to my parents' house and try listening again tomorrow. After all, you can hold it with one hand, and it sounds like this—it's like magic (laughs).
Nevertheless, this small new amp... sounds like a jewel. The Old Sterling sounds as if it is being driven by a well-made 300B amp. Using two of these amplifiers in a mono configuration would be irresistible (laughs). I would like to really enjoy playing good Tannoy speakers with this amp.
