I put a reclocker between my computer and DAC and also used a linear power supply for computer. For me, the reclocker was a bigger upgrade; in this case Singxer Su-6. After looking at all the LPS on Aliexpress, I went with the HD Plex 300W LPS that provides 19V, 12V, 5V, and adjustable voltage.
Add a Linear power supply or iFi SPDIF Purifier2?
I am currently using a Naim Unitiserve streaming from a Western Digital NAS, then using coaxial to a APL DSD-S DAC. I am considering to spend several hundred dollars to add some tweaks rather than spending $2000+ to buy a new streamer/server. I am considering replacing the switch mode power supply with a linear power supply, or the iFi SPDIF Purifier2.
For the LPS, since I am not planning to spend a lot of money, I am going to try one of those from China which the quality is a bit of an unknown. But I think it should still be better than the original power supply.
For the I Purifier2, I read it reclock the signal going into the DAC. However, the APL convert the signal to DSD first. I am guess that conversion should do some clean up or reclocking, so I am not sure if the iPurifier will be beneficial.
Which one do you think will offer a bigger improvement?
