Product Description

The Edwards Audio HA1 MkII is the latest version of this popular headphone amplifier, which sounds truly magical and is excellent value for money. The HA1 MkII is a completely discrete circuit, and is able to output enough power to drive virtually any headphones, and has a very low output impedance.

The line level input and 3.5mm input allow for use with portable music devices or traditional hi-fi sources, and these inputs are selectable via a switch on the rear of the unit. The pre-amp section is now totally active with improved RF rejection. It will happily drive all known types of headphone with ease with its>1W maximum output into 32 Ohms. This is no standard headphone amplifier.

The HA1 MkII offers a big, dynamic sound - grand and rich, but without compromising in detail and delicacy. The mid-range is particularly impressive, and further gains and improvements can be made with the addition of the PSU1 power supply.

By adding the PSU1 Power Supply, improvements can be made to the bass performance of the HA1 MkII - adding weight, scale and precision. Overall dynamics and detail are also improved, making adding the PSU1 a truly essential upgrade.

Press Reviews

  • 'The HA1 is a decent performer and is great keeping everything in check at high volumes' (What Hi-Fi? Magazine)

  • 'The midrange is decently detailed, underpinned by a bouncy bass that steers clear of being overbearing. The clear sound means that you’ll be able to locate separate instruments in a cohesive soundstage.' (What Hi-Fi? Magazine)

  • 'It's a compact and sturdy box whose size belies its dynamic ability – this headphone amp can reach very high volume levels indeed' (What Hi-Fi? Magazine)
