Sugden Audio Products Masterclass HA-4 Headphone Amplifier

Hello,

Up for sale are my remaining Sugden Audio pieces I don't have space for.  I am downsizing my store from three rooms to just a single room.

Sugden Audio is amazing company.  Founded in 1967 known for making some of the finest sounding Class-A audio pieces made and easily the best I have heard.  For those of you not familiar with the Sugden Audio signature sound ... it is rich-bodied ... very tube like but without the hassle of poorly designed tube products.  

The HA-4 is not only a state of the art class A headphone amplifier, it can also be used as a compact high-end pre-amplifier if you wish.  The design is similar to the Sapphire DAP-800 range or products and will drive any dynamic headphone.  The HA-4 features Sugden VCV circuit coupled to a pure class A zero feedback mosfet output stage.  The HA-4 is unconditionally load stable with a discrete constant voltage series power supply.  A high input impedance ensures absolute minimal loss of signal with perfect current gain.

Specifications:

Input Impedance                   20k Ohms

Gain                                      16dB

Channel Separation             >90dB

Frequency Response           >0.3dB 20Hz-30kHz

Signal to Noise                     >95dB

Output Impedance                1 Ohm

While the HA-4 is a listed as demo piece it has only been used once or twice.  It is silver in color and is in like new condition and was built about a year and half ago.  It will come with all original packing, shipping, power cords, manuals, etc.

I am happy to ship anywhere in the world and this piece will ship out 48 hours of cleared payment.

Offers welcome, please no low ballers.  For those of you that like deals, I do have some Audio Note UK (speakers, amps, and pre-amps - level 3, 4, and 5 stuff) I have on hand and keep when I sold ANUK that I would use to sell Shindo and other brands I carry ... so keep an eye out for the ANUK stuff in the near future.

Thank you for your interest and please let me know if you have any questions!
