EXPOSURE’S XM family gets a new member – the HP headphone amplifier, expanding a range that already has an integrated amp, phonostage, preamp and mono power amp.
The XM line is targeted at those seeking “superior audio performance but aren’t necessarily in the market for a hi-fi system that risks emptying their bank account and filling their home.”
According to the literature, the “HP headphone amp is a variation of the XM7 preamplifier but specifically honed for the discerning headphone listener. Like the XM5 integrated amp and XM7 preamp, it includes a built-in moving magnet phono stage and DAC, allowing both vinyl and digital bliss.”
The HP features a linear power supply with a 60VA custom-made toroidal power transformer – only high quality resistors and capacitors are used in the signal path.
Low impedance cans? Not to worry, the HP has enhanced headphone circuitry in which an all-discrete audio output stage delivers high drive capability for such headphones.
The two pairs each of 6.35mm jacks and XLR sockets allow two sets of headphones to be used at once, and there’s also a separate pre-amp output.
