Asus Xonar HDAV 1.3 Deluxe discrete opamp upgrade Brenden H.
The installation process itself wasn’t difficult, but it was quite fiddly. My soldering skills are not all that good, especially for this sort of work, so instead of removing the existing sockets from the card and resoldering the opamps directly to the board, I just plugged each lead into the corresponding position in the socket. […]

Eastern Electric Minimax Dac discrete opamp upgrade by Philippe G.
To be quite honest the results are simply awesome, the Burson discrete op amp transformed the Minimax DAC in a whole new machine seems to work beautifully with the ESS9018, it adds tons of detail, as well as a fair amount of airiness. All in all music gains ‘Gestalt’, a more haptic, tangible experience altogether, […]
Music Hall 25.3 DAC discrete opamps upgrade by Rich O.
I am up and running and the Burson HD op amps are a very worthwhile addition. Wow! The tube side of the Music Hall 25.3 DAC isn’t so soggy anymore. The big benefit was to the balanced SS output, which bypasses the tube and output caps. The bass was kind of soft before, sounded thin. […]

Onix Audio XCD 88 CD Player discrete opamp upgrade by James L.
I tied the clock power source into the 15V (LM7815) regulator. This worked well, for power, as well as the clock seems to regulate down to 15v so I suspect that why it’s built in regulator is barely warm vs hot. The discrete opamps installed well onto the Onix Audio XCD 88 CD Player vertically, […]

…”I have successfully upgraded my old Marantz SR8500 Receiver. One burson discrete opamp for the L-R channels the other for the Centre and Sub.
