Purchased in 2010 from Precision Audio and completely serviced by Threshold Corporation in 2019. I was having issues with the right channel and since it had never been serviced decided to send it to Threshold. I have purchased a Pass XA30.8, a close relative, and havent the room to properly store this 400a. Shortly after having it serviced, the right-channel -12db LED failed - this could be a cold solder joint. Its the third LED on the right side of the display. In addition, the lower left front-plate bolt has broken but has enough of a stem to sit in the hole. Other than those items, the amplifier is in excellent condition and sounds as it should, incredibly detailed. It was driving Magnaplanar 3.7i speakers with ease. Thanks for looking.

This is a box, with outer box, with foams only, nothing else. Original box for Threshold amplifiers. Fits S/500, S/450e, SA/1,S/1000. Foams are in good condition. The most important part of this original box, is the custom crush resistant forms that are made to fit the amplifier properly for safe shipping it, so that the front, back, and heat sinks are well protected during shipping. This box is a must, if you someday plan to ship your amplifier someplace.

Used as my daily driver. Time to move on. In great condition. The amp weighs in just under 70lbs. For shipping I will build custom foam to surround it. It will be shipped in a 2x walled, HD shipping box rated to 100lbs and insured.
