Gustard H10 Headphone Amp Class A, Balanced/Unbalanced, Ex Sound, Powerful, Musical

Top of the line Gustard H10 Headphone amp, balanced and unbalanced inputs, Class A design with beefy power supply and dual mono type configuration, ex clone of a Violectric 200, series of switches on the back to adjust gain settings for left/right channels, original box, power cord and packing. It has always been in a non smoking climate controlled environment. It is in very nice well cared for condition. It sounds excellent with plenty of power. It is detailed, open, dynamic, extended, spacious, transparent, smooth and musical. It is dead quiet. See the impressive specs below. The shipping cost will include fast shipping, insurance and tracking number emailed. Buy with confidence, see my feedback. Good listening, SonnY :)

eatures:
 
1.H10 is a high-current discrete Class A output stage headphone amplifiers, each channel consists of two independent amplification circuit, has RCA inputs, balanced input, you can easily connect a variety of sources.
 
2 machine using a buffer amplifier plus pre-amplification stage main components. Buffer preamp gain adjustment function with four segments, with the four pairs of audio power output circuit tubes on the CPI, you can easily drive a variety of different impedance headphones.
 
3 using two 25W seal ring cattle, independent power between left and right channels, effectively reducing the left and right channel crosstalk.
 
4.AC115V/230V international voltage input.
 
5 Adjust the volume potentiometer placed at the back of the input stage, effectively shortening the audio channel path, reducing interference.
 
6 start-up delay, DC offset, overload, protection circuitry to ensure the safe use of the machine.
 
7 aluminum chassis, before grinding Shahoulasi processes, machines all black.
 
8.RCA single-ended and balanced XLR inputs, input switching and gain adjustment.
 
9 tri-band balanced sound correctly, the output resistance low current, suitable for most headphone mix.
 
10. Rigorous design, reasonable layout, elegant lines, solid materials.
