Headphone amplifier, designed as a cathode follower, allows, in the relax mode, connection of headphones with a wide range of internal resistance without alterations of sound.
Free of output transformers, the amplifier has an incredible frequency range and excellent response, which is very noticeable at the very listening.
Integrated DAC 24bit/96kHz will expand music sources PC or MAC. HA1 can be also used as quality 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.
