HA15

This product is no longer available.
The Hafler HA15 is a high performance analog headphone amplifier that has been meticulously designed to provide an accurate picture of the source material no matter the impedance of the headphone in use.

  • 100% discrete electronics for optimal sound quality

  • Focus control simulates listening to speakers in open air

  • Thru outputs enables greater connectivity options

  • High output to handle virtually any type of headphone

The design begins with a 100% discrete circuit that is completely void of IC's. Although IC's certainly have their place in cell phones and other devices where size is of importance, they invariably employ hundreds or even thousands of transistors to boost the signal then use excessive negative feedback to keep things under control. As the HA15 employs single transistors, negative feedback can be scrupulously added so that the phase cancelling effects are minimized. This results in a much more open and natural sound with virtually zero artefact.

Connecting to the HA15 is done using gold-plated RCA connectors that will not tarnish, thus ensuring a positive connection is maintained. This is supplemented with a pair of THRU connectors to allow greater connectivity options when setting up the system. An abundance of power for the headphones assures the HA15 will gracefully handle any impedance from 8 Ohms to 400 without choking.

To bring greater excitement to the listening experience, a unique Focus control allows the user to activate a matrix that simulates listening to speakers in the open air. In other words, where headphones typically isolate the left and right signals from each other, loudspeakers in a typical acoustic space are heard in both ears. The Focus control lets you dial in as much of the cross-talk to suit while retaining a distinctive left-right mix.

The focus really doesn't do much I might be expecting more but I was lead (led) to believe it would pull the sound around so that you could actually make it seems that the sound was in front of me. It didn't do that. But that isn't my biggest disappointment: I should not be able to comfortably set the volume to max. My ears could hear a lot more volume than this has to offer.

The HA15 is now discontinued but you can still get it - Long & McQuade and some other places offer very good sale prices (L&M price is just out of this world). And if you care about quality - you should get it. Perhaps it is not a Rolls Royce of headphone amps, but definitely a top of the line Lexus. The noise level is relatively low - much lower than in most other units I tried from, among others, PreSonus and ART - and, most importantly, the sound is flat, beautifully transparent, and its quality is pure, that is without shrills when the recording is done properly and you want to hear how it sounds 'real loud'. The Focus option is interesting and it actually works: it emulates listening to your recording through the monitors by widening the aural field within your headphones as you turn the knob clockwise; this feature alone makes the HA15 worth every penny. I noticed - perhaps it's just my listening habits - that you get the best reception of higher levels of loudness (Volume Control) vs aural panorama (Focus) when Focus is positioned at 3:00 o'clock and Volume Control is somewhere between noon and 3:00 o'clock. Of course, you can experiment with these setting to your heart's content. In short: very good headphone amp at a very good discount price!
