British Hi-Fi brand Musical Fidelity is to bring the sound quality benefits of balanced audio to the consumer headphone market – rather than it being the preserve of more esoteric products.
Available in May, the MF200B headphones and V90-BHA amplifier will be available individually for £250 each and as a pair for a special price of £450.
The benefits of a balanced connection are the minimisation of noise and interference in the audio chain, particularly with low-level signals.
The balanced design also allows the MF200B and V90-BHA to operate as a true dual mono system while the balanced audio signal is delivered with effectively twice the power of a single ended version with the impedance halved, making the headphones a much easier load to drive.
The balanced headphone connector between the MF200B and V90-BHA is also much larger than standard headphone jack while its four pin connection and locking mechanism allow for an all-round better, more secure connection.
Based on the recently launched MF200, the MF200B has the same choice of premium design and materials plus the same micro vented, inert enclosure, specially selected and paired 40mm drivers and powerful neodymium magnets of the original model.
The MF200B has also been specifically modified for balanced audio with separate wired inputs into each ear cup, a thicker and better insulated cable, and a 4-pin locking, balanced connector.
The V90-BHA, they tell us, features some of Musical Fidelity’s finest electronics but in a tiny package measuring just 117 X 47 X 70mm WXHXD.
The V90-BHA offers a high input impedance and low output impedance allowing 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 V90BHA also delivers an outstanding signal to noise ratio of better than 109 dB (‘A’ weighted). The frequency response is 20 Hz to 80 kHz (-1dB).
Inputs include both balanced XLR and single-ended RCA while outputs include a dedicated four pin Mini XLR balanced connector and a 3.5mm headphone jack output. The V90-BHA is also designed to effectively run as a dual mono amplifier when in balanced mode, minimising cross-channel interference and maximising stereo separation.
