This simple approach offers stellar dynamics, excellent representation of transients, and a transparent presentation. Using this design for headphones is even more challenging because DHT designs are sensitive to shock, vibration, and electrical inference.\u003c\/p\u003e\n\u003ch3\u003eThe Irresistible 300B\u003c\/h3\u003e\n\u003cp\u003eHA-300MK2 uses a matched pair of Golden Lion PX300B low-noise audio triodes, which are renowned for their dreamy tonal characteristics, as its power output tubes.
