FS is a BNIB Cayin Iha-6 amplifier. It is still sealed in its plastic wrap

Cayin IHA-6 balanced headphone amplifier. I just received this as a replacement under warranty for my broken one. This is a brand new amp. Not a repair and not a refurbished unit. This is a great sounding amplifier that puts out up to 7w +7w at 32 ohm. The amp was even on the inner fidelity wall of fame. I have posted features and specs on the bottom of the page

$579 OBO. Buyer pays shipping based on location and insurance. I will cover the PayPal fees. Retail on this unit is $699
I will add in the Cayin XLR cables (last image) that are the perfect length and stiffness for a DAC and AMP stack for $100 OBO, retail is $200

I wil ship to most countries in Europe or Asia, Australia, etc…just ask and we can work something out.

Message me some questions! I am happy too answer. It is a great amp but I simply need the the money to start rebuilding my set up

Let me know! I am located in Northern California. Please no trades

Thanks so much

Background of i-Series

The i-series is Cayin’s lifestyle solution to modern music lovers. It stands for minimal design, flexible function, premium quality and a total solution to personal audio. To start with, we have introduced the iDAC-6 Audio D/A converter and iHA-6 Headphone Amplifier. More models will be added to this series later on so please stay tuned

iDAC-6 is a dedicated desktop DAC with an interesting dual output stage that offers versatile tonal characteristic for different applications. iHA-6 is a solid-state headphone amplifier with an innovative current adjustment to accommodate different headphone impedance/sensitivity characteristic. When stacked together, iDAC-6 and iHA-6 become a fully balanced headfi system at a less than 10”x10” footprint.

Design Highlight

 Quadruple amplifier circuit with full discrete components and fully-balanced circuit design.

 Independent power supply to Left and Right channel, reduce power interference in left and right channel.

 Innovative Current and Gain control to maxima the compatibility with high or low impedance dynamic headphones and the latest planar headphones.

 Two sets of audio inputs: one for RCA single-end and one for XLR balanced audio.

 Four sets of headphone outputs: two sets of 6.3mm (High/Low impedance) TRS, 1 set of twin 3-pins XLR (balanced) and 1 set of 4-pins XLR (balanced).

 Fashionable design, compact and minimal, can easily blend into SOHO or household environment.

Key Features

 Push-pull amplification design with high power ultra-low on-resistance power MOSFET at power amplification stage, offers excellent dynamic performance.

 Toshiba audio-grade FET were used in differential input circuit, to ensure common-mode noise and high quality audio performance

 Premium grade ALPS 4 channel rotary potentiometer imported from Japan directly, durable, reliable and reputable audio quality.

 Extensive protection to amplifier and headphone through comprehensive protection circuit including output DC offset voltage, delay mute when power up, and noise compensation when power down.

 In-house designed premium grade toroidal transformer with low magnetic leakage and high power efficiency.

 High capacitance filter capacitors were used (in excess of 40000uF)

 Solid chassis with aluminum alloy and sand blast finishing, can eliminate exterior interference effectively.
