Tab 1
Simplicity is the ultimate sophistication.
Leonardo Da Vinci
After several months of research and development, we are pleased to unveil our flagship product - Cloud Nine, our very first portable amplifier intended for use with In-Ear Monitors, headphones, and high impedance headphones. Designed primarily, and most importantly, on improving sound quality. We succeeded on offering better clarity, imaging, and adding more 'slam' to the music by only using the highest quality components. With various features such as reverse battery protection, cryogenic treatment, and a sleek custom made anodized aluminum shielded enclosure, Cloud Nine is the only amplifier you will ever need.
Tab 2
Cloud Nine is an 18V (2x 9V) battery-powered portable amplifier capable of driving not only sensitive in-ear monitors, but will drive even the most power hungry, high impedance headphones - which also means all the IEMs and headphones we build custom cables for will work with this amplifier.

With a precision amplifier followed with dual mono operational amplifier integrated circuits in the output stage, Cloud Nine will provide superior sound quality, excellent channel separation for improved imaging and clarity, unity gain stability, rail-to-rail output, while maintaining ultra low noise and distortion numbers.

Multi gain switch is included (Low for IEMs, Mid for headphones, and High for high impedance headphones)

All 9 volt batteries (Alkanine, NiMH, Lithium) will work with this amplifier and can run from 20 hours to 80 hours. Expect long battery life. [Varies in battery type, mAh, gain, volume levels]

Amplifier features back panel with thumbscrews for easy battery switching.

If you happen to put one or both batteries the wrong way, Cloud Nine has an added reverse battery protection feature to prevent any damage to your batteries and amplifier.

Only the highest quality components are used: Military grade printed circuit board, Panasonic capacitors, Vishay/Dale precision resistors, Texas Instruments ICs, among others.

The power of a full-size desktop amplifier in the size of a small portable amplifier, measuring at approximately 2.3" x 4.5" x 0.95".

Anodized aluminum shielded enclosure, volume knob, and screws are custom made specifically for Cloud Nine.

The entire amplifier goes through cryogenic treatment to improve durability and sound quality.

Cloud Nine is available in black and silver.

Designed and assembled in USA.

15-day money back, 2 year warranty offered.

"The sound of [Cloud Nine and HM-700] is simply amazing, very detailed and everything is balanced, I actually love this setup even more than my desktop setup at the moment..." - Shiorisekine, Head-fi.org

As for performance-by-numbers, Cloud Nine is impressive on almost all fronts… it provides plenty of current into low impedance loads to keep distortion to a minimum while managing pristine frequency responses. It is an excellent earphone amplifier.” - Nathan, Headfonia

“Overall, we’d use the words like “crunchy” or “chewy” with only a little softening of the most extreme tracks, and tons of headroom and space around vocals. Instrumentals feel fast and precise, vocals and bass have a bit of an old-school vibe, with crisp and crystal clean harmonics and percussion. Tons of detail ensure you hear everything, and it’s fairly neutral, flat-response.” - Greg,
TrulyNet

“The Cloud Nine doesn’t sound like any of my other portable amps and I’ve had the opportunity to listen to a lot of different amps. It’s also one of the few amps that does everything from IEMs to Orthodynamics without any effort. Switch the gain, set the volume and enjoy the music. That’s how it works.” - Lieven,
Headfonia

“… Cloud Nine is a very liquid smooth flowing amplifier with a big soundstage… [Starting] at $349.99, the plusSound Cloud Nine really does more than what could be expected… - Cholo Isungga, WhenInManila


"This amp sounds really good!"
"Very impressed. It can easily drive the LCD-2s with ease."
"So far, so impressed. Very well done noise signature and great way of getting into and out of the amp."
"With Cloud Nine, the PR opens up and becomes extremely detailed and revealing."
"Wow! This was exactly what I was looking! Portable. Lot of power. and incredible sound! Amazing product!"
"Very happy with the amp. They can drive my HD800s at only mid gain!"
"Cloud Nine is great. It has the best volume control I have ever experienced on a portable... "
"I have purchased some of your cables in the past, but the Cloud Nine amp is by far my favorite product!!!"
"Everything sounds cleaner, detailed, and balanced. Thanks again for producing such a great product and your exceptional service."
“One word: Amazing!!! It is a significant improvement over other portable amps I own.”
“Top notch sound quality and build. Very impressed, thank you again for the great service.”
