Hi, anyone out there currently running the Matrix M-stage Headphone Amplifier + Hifiman HE-400 together ?   I'm thinking of buying the M-Stage with the OPamp upgrade chip from the below selection with the aim of taming the upper brightness, bringing the mids forward (if that is possible) and...

Obtained this in a trade for my Grado HF-2. Tested both RCA inputs from my pre-amp and it sounds great. The small 1mm scrape circled looks worse than it is since my camera oversharpens; it's on the rear right edge of the unit and doesn't show up from the front/sides/top.   The built-in...

As I am looking to fund a more expensive purchase, I've decided to let this one go to a new home. I bought this from another member last fall.  It's a fantastic amp for the price.  400mw > 60Ohms. Drives my HE-400 well on highest gain. Deep, authoritative bass.  Comes with amp and power cord...

Going with a fully portable rig now as I'm rarely at home. The amp comes with an Australian power cable and full retail packaging. As you can see from the pictures, there's a visible scratch on the side which was there when I bought it new at retail. However, that seems to be the only flaw and...

Hi,   I have $300 budget for the DAC/AMP pairing with Q701. The gear should also has a RCA input to work as an amp alone. Used are acceptable.   M-stage? Compass? These are two gears I found.    It seems M-stage is getting quite a fame. How does Compass(old version, cannot afford the...
