How get this without having to change all the system or a large part of it? How to achieve a substantial improvement with all those features with a very contained investment? 

¿What is The Box?

The Box is a high quality sound device that has been designed to achieve a substantial improvement in an already existing equipment. Just add The Box to your current setup and start enjoying the rediscovery of your sound system and your recordings without having to replace any component. 
What does The Box do with signal?, does it modify it in any way? 
The Box is a completely linear amplifier. It’s normal, without making a good scientific and technical approach, to be unaware of the large energy losses involving cable interconnection of sound devices and interaction with other equipments. All audio equipment, in its input, has a series of filters to reject undesired components, for example, interference or direct current. This filter, seen by the source equipment output stage, is a challenge for it of impedance, capacitance in inductance. In addition, combined with the induction of the cable and its capacitance – typically, its impedance is negligible-. The Box, through a careful design of its input and output filters, its topology and the employment of our AE2270 discrete operational amplifier, of advanced audio design, is capable of making your source equipment immune to all this kind of negative interactions. The effect got is as if you could modify your device source physically to get that had an output section of higher quality. Therefore, the result is like buying a device much more level and price that you have currently, but spending much less money, several times less. So simple. So true.

Adding The Box to your sound system is better than adding the most transparent cable you can afford.

The Box is designed and handcrafted in Spain.
