The latest offering from Hybrid Audio Technologies has been refined over 4 years of development. The highly anticipated Unity line of amplifiers delivers high power in a small beautiful chassis of aluminum and tempered glass. Models include the 1-, 4-, or 5-channel versions for flexibility in system design. 12db variable internal crossovers with bandpass options were incorporated to allow active operation on 2 and 3-way speaker systems. We believe these are the finest amplifiers in their class at any price.
