I have owned one of these for about 2 years. A phenomenal performer. Very clean and powerful. Will drive any headphones. I modded mine by replacing the switching power supply with a linear regulated PSU, and upgraded the DC input cable from the PSU. Unless the amp breaks, I don't see any reason to ever upgrade again. Feed the output from your DAC into this and you will be in heaven.

XetnauqI owned this little amp as well. I totally agree with your said. I do want to upgrade the power supply, could I know which linear regulated PSU do you recommend for this amplifier?

YimingKeep it cheap, keep it Chinese. I have something like this... https://m.ebay.co.uk/itm/2016-NEW-30W-DC12V-HiFi-Linear-power-supply-Regulated-PSU-for-DAC-headphone-amp/111544612626?hash=item19f893b712:g:wdoAAOSw2XFUiC3m The TeraDak power supplies have a good reputation, but they tend to be more expensive. I have also replaced the mains cable with a beefier higher quality one.

YimingBear in mind that the SAPII needs a 24v input. Your DAC may need another voltage.

XetnauqI would like to know the specific products you used for your up-grade, regarding the linear power supply & DC input cable. Links ( if allowed ) would be most helpful. Thanks

XetnauqThanks to mention that. I also have one more question want to ask: I can hear a slightly noise when I use this amp for low impedance headphones. That is the only thing I complain about. So can I kill this slightly noise if I upgrade to linear power supply for this amplifier?

YimingThe lowest impedance phones I use are 32 ohms. I've never heard hiss or hum with no signal fed and volume on max. The whole point of a headphone amp is to drive higher impedance or insensitive phones. The upgrades I did improved clarity, detail and dynamism, but not by a huge amount. I suggest you get some better, high impedance headphones.
