I believe a buffer, discrete or with opamp, would make things work fine.

Default THD and frequency response measurements

Hi,

Did anybody try measuring the THD and the Frequency response of this DAC kit? Just curious?

Many thanks

Just finished building the kit. Mostly used components in hand. No special components used. Measured responses attached. 20kHz low pass filter is used.

Any recommendations for further measurements?

The right channel has slightly more distortion+N than Left channel. I think it is due to more noise in the right channel.

Listening preference: I still prefer my DIY TDA1541 DAC.

DAC 2496 (AK4393) DAC KIT With CS8416+AK4393+5532
Sorry to hijacking this thread, don't want to start new one.
Question is simple: I have an old dac9 ak4399 by Weiliang, which is collecting dust on my shelf. I want to get back to diy, and questioning myself whether I should upgrade this dac to something newer and possibly do more diy or keep using this one.
I am planning to connect it to Moode via Rpi.

Thank you

AK4399 is newer and sounds better.
