I recently sourced out a low power passively cooled computer to run my sml dac.
I ordered a linear power supply off of ebay and decided to buy a iFi Audio iPower 12V ahead of time so I could use my setup. This power supply is powering my pc. and it is connected to the dac via usb.
This is the linear power supply I ordered https://www.ebay.ca/itm/50W-DC-Linear-power-supply-voltage-regulator-DC-12V-3-5A-Upgrade-PSU-of-audio/143131403432?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
Well the power supply showed up today and I was excited to try it out. I do a simple test to make sure the voltage is right and away I go.
Now I have been listening to my current setup for a couple weeks and myself and father in law are very familiar with my considerably better than expected sound quality.
First song I pump in is Jake owen "down to the honky tonk" normally there is a nice hard bass kick and his voice is clear, center stage and very up front. Bass was gone voice was burried.
Second song Gold dust woman, the excellent 3d sound stage gone, and her voice is scratchy it was horrible.
Is this possible is that linear power supply that horrible or is the ifi that good.
Can a power supply mess up audio quality on a pc that bad and any thoughts on what I can do besides throw the linear powersupply out.
