For Sale:
FS: Matrix M-Stage with USB DAC

Will Ship To: Anywhere

I have the following available for sale:


  • Matrix M-Stage amp with built-in USB DAC (24/96)
  • Original box, IEC power cable and USB cable are present
  • The condition of this Amp / DAC is immaculate
  • This is the newest revision of the M-Stage, Model HPA-1, and features the updated power supply 
  • I'm the 2nd owner - Used only in non-smoking environments
  • This amp has the OPA2134 as provided by the factory.
  • This is a Class A amp.  This amp is designed to power headphones with up to a 600 Ohm impedance.
  • I will supply op-amps OPA2111 and OPA2107 with the amp if the buyer desires.  These are new Opamps that I had purchased for another amp.


Link to full specs:





$169.00.  Includes USPS Priority mail shipping.  I will double box this item and safely pack it for shipping.  I will cover the PayPal fees, too.


I am using stock photos to depict the amp I'm selling.  I will also ensure the buyer that this particular amp is in excellent shape.  Original owner had it for approximately 6 months.  I just received it and took ownership.  However, I also stumbled on a deal for the Beyerdynamic T90s after buying the Matrix, so I have to replace some funds.
