With the launch of the V90 - BHA headphone amplifier and its partner MF-200 B headphones, balanced audio technology is no longer only for esoteric products.
The benefits of balanced connection have long been known in the pro-audio industry, where great efforts are made to minimize noise and interference in the audio chain, particularly with low-level signals.
By using balanced connections, rather than single-ended audio, RF interference on the audio signal is effectively cancelled out, resulting in an exceptionally low noise level and a far more accurate sound.
The V90 - BHA offers high input impedance and low output impedance, to allow connection to most sources and the ability to easily drive the vast majority of headphones ( from 10 ohms to 600 ohms ).
Distortion is very low, typically less than 0.005% across the audio band. The V90 - BHA also delivers an outstanding signal-to-noise ratio of better than 109 dB ( ‘A’ weighted ). The frequency response is 20 Hz to 80k Hz ( -1dB ).
Inputs include both balanced XLR and single-ended RCA, while outputs include a dedicated four pin Mini XLR balanced connector and a 3.5 mm headphone jack output, making the V90 - BHA a very versatile headphone amplifier.
The V90 - BHA’s combination of very low distortion, extremely low noise, flat frequency response and low output impedance gives a smooth, effortless sound quality normally reserved for far more expensive products. The V90 - BHA is also designed to effectively run as a dual mono amplifier when in balanced mode, which minimizes cross-channel interference and maximizes stereo separation.
The V90 - BHA features some of Musical Fidelity’s finest electronics, in a tiny package that looks great, with a front panel and cover of custom-made extrusions, finished in fine-texture moonstone.
