It is a great step forward in exception sound, with a new and original technical approach.

D.R.E.i. Technology (Dynamic  Reduction of Electronic  Interactions), developed by Neutral Audio is an advanced implementation of analog circuits to get maximum enjoyment from musical reproduction.

When the first requirement of development is the use of only analogical components of the highest quality, without using digital components of any kind and without cost considerations in the search for excellence, the problem is more complex.

The result of so much effort and dedication is an independent module that can be inserted into any suitable audio equipment that allows its installation such as audio sources like CD players or preamplifiers  - where it shows its highest potencial -, in phono-preamps and in power stages, amongst other things.

You get clearer, more precise natural sounds, the dynamics being drastically increased, the space between channels is even greater and the diferent sound levels are realer.  You will be able to hear sounds outside the angle of the loud-speakers that were always there but could not be heard. Live sounds really come alive, minimizing the acoustic problems of rooms and increasing maximum sound pressure potential before saturation is reached.

It adjusts and corrects the errors caused by electronics due to their inevitable and accumalative tolerance errors. Small musical details that are normaly fuzzed because of electronic interactions that happen in any circuit, suddenly appear with great strength and realism.  It separates the different instrument and voice tones and it enhances them to the point of being able to discern great orchestral and coral masses.

It gives voices, affected by the digital circuits used for recording and reproduction and obscured by the fuzz of instruments, their texture back. The deep notes are stronger, perfectly defined and harmonious and there is an absolute control of the reproduction of complex sounds.

To sum up, music flows smoothly, crystal clear and neutral.

This label certifies that the equipment incorporates technology and meets all specifications.

Chap. 2: D.R.E.I. technology

Musical signals enter the device and once amplified and processed are sent  to various independent preamplifiers, between 2  and  6  which are dynamically controled by D.R.E.i.  The ouputs of the different preamplifiers are remixed in a wholely passive way and without any other additional active circuits, so as not to add electronic interactiones outside the D.R.E.i.’s control.
