If you are looking for products or advices to improve the quality of the amplifiers that you intend to design and build, or if you want to upgrade an existing one, then this site will be helpful and will surely meet your expectations.
For many years, we have seriously worked to study, think and develop new approaches in the audio reproduction field and are now very pleased to suggest modern circuits and novel output transformers that will make a noticeable difference in the quality.
We support project designers and audiophiles that want to build their own amplifiers in a "different" way, avoiding the too common last century layouts.
You will find several articles that will widen your views on the matter and surely raise your interest and desire to achieve outstanding results.

Information
WELCOME TO THE SITE OF DEMANDING AUDIOPHILES.
Here you will find new ideas, as well as novel audio circuits and transformers.
These are not the same that were popular over half a century ago, but new ones that ensure a significant improvement of the quality of the sound.On this site, you will discover a new philosophy, based on extreme simplification of sound reproduction devices. You will also learn about a novel line
of output and interstage transformers, that have been exhaustively tested, patented and described in many wellknown specialized magazines. You will be able to ask the author and the tech-team, on a one to one basis, questions about the circuits and products that interest you. The answers you will receive will be comprehensive, in-depth explanations. Finally, you will notice that your mentality will adjust to the innovative drive of designing and building audio amplifiers and some of their accessories.
You will be invited to submit suggestions, ideas and proposals with absolute confidentiality.
Direct coupling means avoiding the use of coupling capacitors as much as possible.
D.C.M.B. (DCMB) is the system that connects the driver unit to the power unit in an absolutely intimate way, relegating the capacitors to the power supply unit, where they are essential.
Describing the Direct Coupling Modulated Bias layout (DCMB)
Comparing the DCMB to existing similar circuits
More on the DCMB
Advantages of the DCMB
The hidden side of the DCMB effects.
Part two – Suitable transformers that increase the sound quality
The SC-OPT – self compensating, for Single Ended amplifiers, with its outstanding feature: the “Flux escapes”.
The SC-SCC transformer using one magnetic circuit for both channels. Its unbelievable frequency range fills the stage with a warm, consistent and crystal clear sound.
The 4x4 Transformer – requiring pair(s) of valves and ensuring full self compensation. It also avoids the need of matching the valves used.
The YxY transformers family, combining the merits of the above transformers (self compensation, extended range, absolute channel separation, auxiliary power level and frequency controls).
Be ready to learn about the future developments of our audio transformers.
