The Edwards Audio HA1 Mk2 is a fully discrete, two input Bi-Polar headphone amplifier. The inputs are relay switched via a rear panel toggle switch and allow for standard RCA line level input with loop output, so you donâ˛t lose an input, plus a dedicated MP3/iPod input on 3.5mm stereo jack. (Trade marks acknowledged)
Designed to have a very low output impedance it uniquely features a fully regulated power supply which both lowers noise and increases the dynamic range. 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 headphone output jack is a professional quality 6.3mm 1/4â Neutrik type which will prove very robust over many years of use. Now with a back lit blue LED display, this is a very modern and stylish product.
The sound quality is totally effortless with big out of the head imaging with clean clear fatigue free dynamics which creates a very musical performance that totally belies this diminutive box. This actually makes headphone listening enjoyable.
It has all the usual Edwards Audio styling and gold plated PCBâ˛s but most importantly is also covered by our 10 year guarantee
With an incredible ÂŁ279.95 UK price tag this is sure to upset more than a few apple carts.
