Selling this awesome headphone amp as I don't use headphones that require this type of quality anymore. The unit is in great condition, comes with a remote, a power cable and a USB cable. Specifications are as follows: HIGH PERFORMANCE AUDIO - Discrete Class A Amplifier A Class A amplifier conducts signal over the entire range of the input signal cycle. The output transistors are biased to operate in their most linear range, and there is no crossover distortion caused by switching the signal between two push-pull devices. The HA-1's power amplification circuit for the headphones is Class A built with discrete transistors. The discrete design allows us to hand-pick and match the best parts to build the HA-1. - Toroidal Power Supply A toroidal power transformer offers superior power efficiency and much lower exterior magnetic fields over traditional laminated steel core transformers. The HA-1's toroidal linear power supply provides a very clean and robust power source to the audio components. - Fully Balanced Design The internal analog audio signal path of the HA-1 is fully balanced. For digital audio, the signal runs in balanced mode all the way from the DAC to the output jacks. Balanced analog input is kept intact, and single-ended input is converted to balanced at the input buffer. All single-ended outputs are derived from the balanced signal as well. The balanced design provides better common-mode noise rejection and improves signal quality. The balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones. It also provides better channel seperation by eliminating the common ground return path. - ESS Sabre32 Reference DAC The DAC is one of the most important components for digital audio playback. The SABRE32 Reference ES9018 from ESS Technology is the world’s best performing 32-bit audio DAC solution targeted for high-end consumer applications and professional studio equipment. With the ESS patented 32-bit Hyperstream™ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference DAC delivers an unprecedented DNR (Dynamic Range) of up to 135dB and THD+N (Total Harmonic Distortion plus Noise) of -120dB, the industry’s highest performance level that will satisfy even the most demanding audio enthusiast. To learn more about the technologies behind the exceptional performance of the SABRE DAC, please read the SABRE Technical White Paper. - Clean Signal Path The HA-1 uses an analog potentiometer (the familar volume knob) to control the volume. By avoiding re-digitizing the audio signal for volume adjustment, the HA-1 provides a clean signal path for the audio. At the same time, the convenience of modern digital volume control is not lost - a remote-controlled motor turns the volume knob and a 10-bit analog-to-digital converter samples the signal to display a numeric dB level. - Made for iPod®, iPhone® and iPad® The HA-1 passes Apple's "MFi" certification and is compatibile with the latest iPod, iPhone and iPad to be used as the digital audio output accessory of these devices. By tapping directly into the digital audio signal of these devices and converting the audio to analog using the high performance SABRE32 Reference DAC, music from your favorite portable device will sound its best. - Wireless Audio via Bluetooth The HA-1 supports Bluetooth Advanced Audio Distribution Profile (A2DP) with both the standard and aptX® high quality codec. Simply pair your phone with the HA-1 and set music free wirelessly from your mobile phone. - Asynchronous USB DAC By bypassing the low fidelity, poor quality DAC of traditional computer soundcards, the HA-1 turns any computer into a high performance multi-media source by converting digital audio to analog through the ESS Sabre32 Reference DAC. The asynchronous transfer mode uses the high

    iFi Audio Micro iDSD DAC and Headphone Amp - with Pre amp Variable out. There is nothing like the micro iDSD. It is literally, out of this world. It is the only DAC in the world (at any price) to play True Native Octa-DSD512/PCM768/Double DXD. Its Perfect-Match means it can be fine-tuned to any headgear from IEMs all the way through to large headphones. Its 8v/4000mW output makes it one of the most powerful headamps to drive even the most hungry of headphones with ease. iFi has forged an enviable reputation for being at the forefront of computer audio technology. The micro iDSD has just made another leap, an Octa-Leap to be precise. With its special Dual-Core Burr-Brown native DSD/PCM chipset at the heart, the micro iDSD is capable of True Native PCM768, Octa-Speed DSD512 and 2x DXD; it is simply out of this world. The micro iDSD has 3 different power modes Eco, Normal and Turbo. Capable of 4000mW, 1000mW or 250mW, the micro iDSD is able to drive the full gamut of headphone and amplifiers alike. With iEMatch there to dial to suit any IEM, the micro iDSD has redefined the headphone amplifier class. Used along with the analogue volume control, the diminutive size of the micro iDSD belies its uncanny ability to drive virtually anything and everything! SmartPower® is the micro iDSD’s onboard recharging feature for Smartdevices. Its 4800mAH battery is able to fully recharge an iPhone two-times. Compatible with Apple and Android, phones and tablets, it is another example of iFi’s commitment to customer needs – enjoy high-end audio on the go without worrying about the phone going flat. iFi’s iCAN and iTube have already achieved widespread acclaim, so much so that their core features including 3D Holographic and XBass have become renowned in their own right and imitated by others. In the micro iDSD, for the first time in an iFi product, it features XBass and 3D Holographic for Headphones and Speakers. All these features are still executed in the analogue, not digital domain to preserve the original music format. And so much more….with the amazing Crowd-Design program, we are over the moon that you, the customer was central to the development of the micro iDSD.
