Akiko Audio Ground Conditioner Castello Solo

€ 1.295,00 each


Akiko Audio Ground Conditioner Castello Solo. Specially developed for the Akiko Audio Power Conditioner Corelli.

The Castello Solo is a newly developed variant of the standard Castello, which works excellently in conjunction with the Akiko Audio Corelli power conditioner. The internal ground unit in the Corelli is supported by the Castello Solo, enhancing its noise-reducing effect. In a good music system, the use of a Solo is immediately audible. The Ground Conditioner Castello Solo has one compartment and is equipped with one connection, which is connected with a ground wire to the Power Conditioner Corelli.

The Castello Solo is specifically designed for use with the Corelli but can also be used in combination with other equipment such as streamers, preamplifiers, and CD players.

Over the past years, we have gained a lot of experience in reducing the noise floor in the rendering chain. Noise is an unwanted signal that affects all connected equipment in your audio and video system. The ground in the power supply has a more complicated task than is usually assumed. The Ground Conditioner Castello Solo operates independently and is therefore not affected by other power consumers in your home. The compact unit is passive and forms a zero-reference for your music system. High-frequency surface current seeks a low energy point and will use the Ground Conditioner as ground.

What improvement can you expect:

  • A very honest, relaxed, and neutral playback.
  • Improved dynamics and spatiality.
  • Music is experienced as more natural and cleaner.
  • Remarkable improvement in vocal reproduction and reproduction of acoustic instruments.
  • Due to the reduction of high-frequency noise, listener fatigue is not given a chance.
  • You listen deeper into the recording; due to the lower noise floor, small details become even more audible.
  • In short; the use of the Corelli-Solo combination provides even more emotion!

Placement: Next to or on your equipment, or on the floor. Placement is not critical.
