Selling off my USB tweaks since I'm using a streamer now.  This is an iFi Micro iUSB Power Supply ($229) and an iFi Gemini USB cable (1.5m)($265).  I bought these from the first owner 11/2013.  Both are in great condition, 8/10 on audiogon scale.  Selling as a package deal for $250 shipped to the US.  I will also eat the paypal fee. All original packaging included.
Here is some info:

iFi iUSBPower Power Supply

The iUSB Power is the World's Only Ultra-Quiet USB Power Supply - Quieter Than a Battery

Bypass the Noisy USB Power from Your Computer and Replace it with Fresh, Clean Power

Lower Your System's Noise Floor and Increase the Analog Perspective from Computer Audio Files

You've never seen or heard anything like the iFi iUSBPower because there's never been anything like it. The world's quietest USB power supply, it removes noisy USB power from your computer and replaces it with clean power, eliminating any pollution corrupting your data. Designed to be the best power supply for all audio devices, no matter the price!iUSBPower boasts a Super Regulator purified power supply, the innovative IsoPower connection system, and IsoEarth technology. Use the iUSBPower with any DAC, and the level of sonic improvement you'll hear will be shocking. Pair it with the iFi DAC or any USB DAC in the world, and you'll be in heaven.

"In my nearfield desktop system replacing the stock AC power supply with the iUSBPower lowered the iDAC's already low noise floor to the point where it sounded very much like what I'm used to hearing from a live microphone feed. Micro-dynamics seemed more pronounced when the iUSBPower was attached and the smallest details buried in the mix were easier to hear."
– Steven Stone, The Absolute Sound

Super Regulator Technology Combines Purifying With Filtering
At its core, iUSBPower lowers the noise floor, enhances microdynamics, delivers whisper-quiet soft passages, improves sonic richness, and unearths important musical details. Quieter than a battery, it elevates the vibrancy and lifelikeness of any music you play. Its Super Regulator technology encompasses multi-stage and multi-order power purifying with filtering. An audio-grade USB power-supply unit and incredible voltage accuracy help explain why the iUSBPower supplies the cleanest power ever.

"This has some serious implications for the deluxe music server sector. Why spend $2-3k building a bespoke PC or buying off-the-shelf megabuck servers when a $200 appendage will soothe EMI/RFI nerves on ANY device with a single clunk-click? At that price, EVERY serious digital audiophile should have one. A round of applause, please."
– John Darko, Digital Audio Blog

An Entirely New Way to Connect Your USB Audio Device
More than just a stunningly quiet power supply, iUSBPower offers an entirely new way to connect your USB audio device. Sure, there's the standard USB option. But taking into account the iFi dual-path USB cable, iFi's IsoPower system allows you the opportunity to run separate power and audio data lines - much like you already do with separate interconnects and power cables. IsoPower eliminates any pollution between data and power lines, keeping your USB data free of contamination and removing USB signal noise from power-supply lines. You'll hear your USB devices perform at their maximum ability.

"This was another review where it was mostly all fun from the first to the last notes played through the iFi duo."
– Michael Lavorgna, AudioStream

Reduces Ground Noise by a Factor of 10
Specifically developed for the iUSBPower, IsoEarth breaks the noisy DC ground connection between your computer and your USB audio device, further reducing ground noise by a factor of 10! With the iUSBPower, your device will operate in the cleanest-possible environment, affording music to flow through unimpeded and with utmost transparency.

Not an Add-On But an Essential Audio Component
If you're serious about sound, there's no reason not to at least give the iUSBPower a shot in your system. It's 100% Music Direct Money-Back Guaranteed. And it'll have you wondering why it took so long for a manufacturer to come up with its likeness. Thanks, iFi.

iFi Gemini Dual-Headed USB Cable

The Only Cable of its Kind to Fully Separate the Power and Audio Signal

Superb Connectors, Incredible Shielding, Custom-Designed RF Shielding All Standard

Another first from iFi: The progressive manufacturer's Gemini is the only USB cable of its kind that fully separates the power and the audio signal in two cables, netting grain- and edge-free music reproduction. Gemini's special geometry adheres to the 90-ohm impedance specification even better than the USB 2.0 standard. In addition, FINAL USB machined connectors provide stellar end-to-end shielding while custom-designed triple RF silencers provide the widest possible filter range without affecting the USB signal. Sonically, Gemini is the cable you want.

Avoids Interference and Geometry Issues Common to USB Cables
By carrying audio and power in two separate cables, Gemini avoids the interference issues that plague common audiophile USB cables, particularly since power is heavier gauge and audio lines possess more cores - to say nothing of geometry distinctions. In Gemini, power and audio signals are thus individually transferred and free of transmission problems. Your music will sound the way the artists and producers intended.

FINAL USB Connectors Provide Remarkable Shielding
While the fact that signals run through both the cable and the connector is common knowledge, a majority of USB cables cheap out on the connector by using molded plastic covers. But since plastic cannot shield the high frequencies in the USB data link, noise radiates out and sound is compromised. Durability also becomes a troublesome issue. iFi eradicates any such problems by using FINAL USB connectors that afford superior end-to-end shielding. Machined entirely from solid aluminum and gold plated, they are the new standard in connectors.

Enjoy the Silence 
Outfitted with three custom-made metal oxide ceramic RF noise silencers that cover different effective ranges, Gemini even addresses RF issues - most other cables ignore it. Not only does Gemini broaden the range over which RF noise is silenced, its middle silencer is adjustable in order to "detune" the antennae formed by the cable depending on the system conditions and requirements. None of the wide-range RF silencers affect the USB signal. Enjoy the silence.

Pair With the iFi iUSBPower for the Ultimate in USB Quality
A twin that dares to be different, Gemini attains zenith performance when paired with the iFi iUSBPower power supply, forming a combination that delivers the ultimate in USB audio sound quality. That two compact, budget-priced audio devices can produce such divine results is almost unthinkable. But as iFi keeps proving, anything is possible.
