I have a Rudistor NX-02 headphone amplifier for sale. I decided to switch to a tube based headphone amplifier so I no longer need this amp.Audio review: http://win.rudistor.com/Docs/aff-audio-sistems.pdf Manufacturer's Information: "The NX-02 offers clear, natural sound with a wide frequency response to give you the feeling of listening to live music. The system can drive any set of headphones with an impedance between 4 to 1000 Ohms, and two front-panel headphone outputs allow you to listen with a friend. The NX-02 has been designed to offer ultra-low distortion at all frequencies and volume levels, and provide a completely flat linear response, allowing it to easily drive small speakers. No capacitors are used in the signal path, so no global negative feedback is used. The amp has a totally silent noise floor of -113dB, making this an ideal amplifier for listening to SACD or DVD-A media. In addition to great components for sound quality, protection circuitry has also been built-in that performs a safety check at start-up and continues to monitor working conditions. If an unsafe condition is detected, the amplifier will electronically disconnect your headphones from the amp to protect them from damage. Durable design, created by Ultrasone and RudiStor Drives any headphones with impedances between 4 and 100 Ohms Two headphone outputs and a large volume control Clear, natural sound with a very wide frequency response Ultra-low distortion Flat, linear response for an ultra-high damping factor Totally silent -113dB noise floor, ideal for SACD and DVD-A" I'm asking $145 plus shipping or best offer. I accept PayPal but the buyer is responsible for paying their fees. I also accept USPS money orders. I will only ship within the USA. I will consider trades. I have great feedback on Ebay as Gelajoy (900+ rating at 100%.)
