"I feel the Hafler HA75 is a compelling choice for a headphone amplifier - for all of the reasons that one would expect with a well implemented tube-based design. The extra depth in the soundstage and the tiniest bit of fullness to the bottom register translates nicely to what I'm used to hearing when listening on the big monitors in the mastering studio."
The Beatles, Pink Floyd, Al Stewart, The Alan Parson's Project
