→AMATERAS 0001 makes sound much better, increases the sound pressure level, I recommend this.
→I thought it wouldn't make much difference, but the sound completely came out of the shell. It feels so good. This equipment is amazing.
→I bought the AMATERAS Line Trans. "Texture that cannot be reached no matter how much digital processing is made" was true. The key to tight, sticky, clear sound is a good transformer.
→AMATERAS Line Trans is really good.
I tried for vocal, and the sound became clear like it took off its veil.
→AMATERAS Line Transformer is so good!!
There's so much more cohesion in the sound, and the presence of each piece of sound is incredible!
It's like stripping away the useless part and spreading the only good part.
Also, the sound seems to come on really fast.

 The Essence of High-End Audio Transformers

Transformers are fascinatingly analog devices at the heart of audiophile sound. They operate by converting the audio signal into a magnetic field using a coil, transmitting it across an air gap, and then transforming it back into an electrical signal.
Ideally, a transformer should transmit the audio signal without any alterations. However, the physical properties of the transformer, such as the winding method of the coil and the material of the core, inevitably introduce subtle changes to the sound quality.
The art of crafting high-end audio transformers lies in harnessing these inherent changes and "transforming" them into musical enhancements. Through meticulous design and the use of premium materials, these transformers can elevate the audio experience to new heights.

 Industry's highest cost rate

〜The reason why it is only available here〜
Usual cost rate you see for audio equipment is 30% but we offer 50-60% . This is possible because we have a direct deal with manufacturer unlike some having retail store or distributer in between who takes margin. All of our products are made with high quality parts that would not be accessible to big producers.

We deliver to most countries in about 10 days from Japan.
