Neodio HQA Amplifier – High Quality Amplifier

HQA High Quality Amplifier

For those who want the best and want it to last.

Background

Progress can have different faces. On the one hand, there is triumphant technology, with products that are increasingly complex and constantly being upgraded and replaced. On the other, there is a more rational form of consumption, that is mindful of natural resources and sustainability.

In developing the HQA, every effort has been made to ensure that the product has the maximum possible life span. It comes with a 10-year guarantee to the first owner, and I’ve designed it to be easy to repair and, if necessary, upgraded in the future. The HQA is a product designed to stand the test of time.

To achieve this, I simplified everything that could be simplified and went back to the essence of what an amplifier should be: a machine that is faithful to the music and capable of satisfying its owner for many years. It has no remote control or display, just a switch. This minimalist approach allows us to focus on design quality, build quality and sound performance.

The quality of the design is based on 20 years’ experience in the development of amplifiers, digital sources, cables and accessories. Behind the apparent simplicity of the HQA lie numerous essential electronic, mechanical and wiring components.

To ensure high-quality manufacturing, our French and European subcontractors are chosen for the care they take in their work. The mechanical parts, electronic board, assembly and packaging are all produced/carried out in France. The transformer is made in Spain.

Electronic configuration

The HQA uses a classic 3-stage architecture with high negative feedback. Negative feedback is a highly effective technique, provided attention is paid to the practical details of its implementation. It took me three years to achieve the result I was hoping for. My version of the negative feedback lies on an innovative circuit that gives a plus to the sound quality. A dynamic, controlled sound, typical of negative feedback, but without the stiffness and unnaturalness often associated with this technique.

The amplifier for those who want the best and want it to last.

Implementation

Cabling and connectors

We have chosen components that guarantee the best sound quality and durability:

• RCA inputs with high-quality gold-plated insulated plugs
• XLR inputs for the compatibility with balanced preamps or sources
