I understand that to improve sound quality, we should use linear power supply.
First, I hardly find where to buy these, and secondly, when I think I found one, it is as expensive as my whole system.
My system is like this: Cubox-i (spdif) > PopPulse PCM1796 MKII DAC > Trends Audio TA-10.1 Amp.
Each component uses its original power supply. I understand that I will need to buy a new linear power supply for every component, right?
Do any of you have experience/hear about that Chinese linear power supply?

If it’s garbage, would you please point me to something better about still affordable?
