Trouble Shooting:
Q: Right channel has static. Tried different source and headphones. No help
A: If there is static noise in one channel, normally it is caused by the tube of that channel. Maybe it has a poor contact after the long shipping process. You can open the chasis and adjust the screw near the tube while listening(contact us and we will give you a photo with marks to help you find it). Also, there is a small possibility that the tube is broken. You can buy a 5899 tube in local shops, which is very normal to see. And we will refund you the cost.
Q: It broke just now four loud pops and it's dead. Very disappointed.
A: Mainly because the battery is run out of power. Please charge it. If not help, please contact us.
Q: The Amp has a lot of electronic feedback/interference when a cellphone is hooked up to it or nearby. It creates popping in the headphones.
A: Vacuum tubes are easy to be interfered by devices that can trandfer siganl like cellphones, routers. Please keep the amp away from them.
Q: Won't hold a charge, sounds like something is loose inside.
A: The charger is broken. Please contact us to get a new one.

Schiit Magni 3 Headphone Amp and Preamp

Check Price on Amazon
Buy headphone amplifier best buy from Amazon.com

Description:

Go ahead. Compare the third-generation Magni to anything out there at its price. We think you'll find there's really no competition. This is no "starter amp." Magni 3 has the power, performance, resolution, and versatility to meet all your needs-no matter the headphone.

  • Ready For Any Headphone
    Magni 3 is ready for any headphone, from IEMs to hard-to-drive planar designs. With a full 2000mW into 32 ohms-rated in the most honest way, RMS continuous, both channels driven-Magni has tremendous reserves of power. Combined with low distortion, an exceptionally low noise floor, and switchable gain, Magni is ready for any headphone.
  • Powered Monitors Welcome, Too
    Magni 3 includes preamp outputs. This means you can connect it to your desktop powered monitors for a complete system-or even connect it to a speaker power amp and use it as a preamp. With its built-in time-delayed start-up and instant shut-down, there'll be no glitches or pops through either headphones or speakers, either.
  • Forget 99--Compare at Many Times the Price
    Most headphone amps in Magni's price range use op-amps (integrated chips) for gain and power output. Not Magni. Magni's gain stage is an-all-new, fully discrete, high-speed, dc-coupled, current-feedback design, completely different than the first and second-generation Magnis. This current-feedback gain stage is typically only found in very exotic designs that sell for more than 10x the Magni's price.
  • Designed and Assembled in USA
    The vast majority of the total production cost of Magni 3--chassis, boards, transformers, assembly, etc.--goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Yes, the wall-warts are made in China, but there's some give and take at this price point.
  • 2-Year Warranty
    Magni is covered by a limited warranty that covers parts and labor for two years.
