Paradise in Your Room!

Purpose of This Website

I began, in 2010, writing "Tonochi's Audio Room" in order to put my experiences as an audiophile in writing. I am only an amateur, though, I have experienced many things in my hobby, DIY audio, since 1970. Now I have my own point of view and methods in this field. I believe showing my experiences to public is meaningful in any way for people who are interesting in DIY audio. I'd appreciate if readers would refer to this website as a helpful information.

I wish that not only experienced audiophiles but beginners and music lovers visit this website.
I was originally a liberal arts student. Now I can design circuits, PCBs and simple mechanisms. My designs may not as good as ones designed by professional engineers, but my audio equipment is as good as my friends praise very highly. Anyone with enthusiasm can build his/her own unique audio devices. I'd be very happy if any readers would take up DIY audio by being inspired by this website.

This website is originally written in Japanese. I would like this website to be read by non-Japanese people. So I created this English edition. The contents are the same as Japanese edition.
These days, machine translation (automatic translation) technology is advancing in quality, though, I translate my website by myself, because I'd like to express my opinion by my own words.

About Gaudi Project

In 1974, when I was 17, I concluded that the best audio system is 3-way multi-amplifier system (triamplified system), and started building it. I decided to build every component myself since I didn't have deep pockets. It was so difficult to build everything in a short period that I took a step-by-step strategy and started with a simple mono amplifier system.

It was a 5-year plan at first. But there was no good progress. The plan was revised to a 10-year one, then a 20-year one... There seemed to be no end.
In 1999, it seemed to me that I couldn't complete my audio system by the end of my life, and my system is like Sagrada Familia desinged by Antoni Gaudi. I named my audio system after the name of the great architect: Gaudi. And, I named the plan Gaudi Project.

Gaudi was completed in 2015, though, I decided to continue the project because I thought I could improve Gaudi system further by utilizing what I had learned from Gaudi Project.
I name the new system Gaudi II, which means Gaudi Version 2. I plan to make it the audio system of the highest sound quality.

On this website, the main theme is the system design of Gaudi II and its implementation. Because I believe that the system-oriented approach is fundamental to realize the best sound quality.
As of February 2021, the system design is completed, but the implementation has just begun. I hope the readers enjoy the process of building the audio system together with me.
