I have installed 2 dual Burson op amps in my Rotel RCD991 CD player a few days ago.
Could not beleive the difference. I’ve stayed awake until 5am just to enjoy “new sound”.
These op amps have released Rotel’s full potential, sound is just amazing!
Were there any other mods? Was there anything else replaced or just the op amps? Any changes to power supply for the difference in sound?
Yes, power supply upgrade always worthwhile.
