This is an advice for all of you using the hypex ncore modules thinking they have to much gain , if you know how to desolder SMD components .
The ncore 122 module has a gain of 25,5 dB .
The ncore module 122 and more, can be modified by desoldering two smd resistors at the buffer stage , lowering the amplifiers gain about 12,5 dB . The opamp buffers now act as unity gain buffers, making the amplifier perfect to drive directly from a dac .
In my case , I use a WiiM ultra as digital preamp using toslink to my rega dac . The rega is directly coupled to my Audiophonics ncore 125 power amp.
Before the gain modification , I could only play music at about 25 ( out of 100 ) on the Ultra volume display.
After desoldering the two resistors , lowering the gain of the amplifier, the digital volume control on the Ultra is often used at 50-60 meaning less digital information is lost and the sound gets slightly better .
