Grace Design m201 mk2

Περιγραφή

 Freshly redesigned the m201mk2 provides a full serving of our unique brand of audio performance. It delivers massive headroom, ultra-wide bandwidth and a very open, musical character.

The fully balanced signal path has been refined, resulting in incredible dynamic range. A new power supply design provides the lowest noise performance we have ever achieved. This all means the new m201mk2 will translate a sonic picture of astonishing clarity and detail, which captures the essential character of the music being recorded.
