Hello ! Just bought K11 dac/headphones amp, here is board photo with some measurements. There are 18 regulators, with 2 independed amps for 4.4mm phones. First of all I don't like polymer caps in analog circuit, and already swiped one op amp to opa1656. Maybe the pictures will be useful for someone to repair
Of course this should be an amount not exceeding the cost of the device itself, but I'm don't thinking seriosly about this, it is a hobby so it is not important about money. I expect this can sounds better, amount of better at this time is hard to measure ))
Now I'm thinking about choosing a power supply, have three interesting variants: Base On STUDER 900 Circuit Power Supply, S35-MKII Fully Discrete HIFI Linear Power Supply or board with 4pcs LT3045 in parallel
