Stereo amplifier for headphones with integrated USB DAC (24bit/96 kHz) and output transformers at the exit. Depending on the headphone type (resistance), the output impedance can be selected by a knob switch. 30, 60, 150 and 300 Ohm.HA2 is also a vacuum tube preamplifier
|Specificatii||Why Tube Amplifiers?
After decades of solid state amplifier innovations, tube amplifiers have staged a powerful comeback in the last ten years, due to their sonic merits:
Tube amplifiers distort in a different manner from transistor amplifiers, generating musically agreeable even-order harmonic distortion that may lend a sense of so-called warmth to sound and it's this characteristic that most tube aficionados prefer.
While tube amplifiers are often not as smooth or linear in frequency response as transistor designs and have other liabilities as well, when pushed near or past their output limits, tubes tend to gracefully distort, without the harshness associated with transistor clipping.
