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. […]

Firestone Cute Beyond headphone amplifier discrete opamps upgrade by R. Carstens

A notable difference and improvement for these discrete opamps over other IC operational amplifiers tried in the Firestone Cute Beyond headphone amplifier, including the old time favorite OPA627.

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, […]

With some help, i remove all the components interesting by the tweak on my Oppo BDP-83 Blu-ray Player 83. 2) i plug your two discrete opamp (before op CMS ,it’s very small for my old eyes!). 3) I make myself a power supply with old toroidal transformer 250VA !! 220v-15/15v (salvage in my factory), régulateurs […]

McIntosh MX-136 discrete opamp Mod by Neil H

Finally the McIntosh MX-136 is up and running again. Fitted the discrete opamps but unfortunately ran into a problem where one channel stopped working… Eventually tracked it down to a signal ground having an intermittent connection. I have just finished watching a movie and the sound difference is amazing. The sound seems considerably more dynamic, and […]
