With the shanti…what Output to you use? 5v/3A or 5v/1A? Also…has anyone tried the Topping P50?

I use the 3A output from the Shanti. Imo it sounds a bit more dynamic than from the 1A output.

I use 1A as this is more than sufficient for Qutest. The 3A rail powers my Pi4

Have you tried the 3A to see if you hear an audible difference?

It will not work the other way round as the Pi requires more current. Any comparison would then involve using the original Pi power supply, so not a worthwhile exercise. It is my belief that the Pi benefits more from the Shanti than does the Qutest.

Has anyone tried the Topping P50 with the Qutest?

I have recently got a Sbooster mk2, with which the Qutest has finally started to sound as it knows. I come to say that with the stock power supply, the Qutest is not worth the money it costs: harsh and fatiguing sound.

I would upgrade the fuse on the LPS for the Qutest.

I upgraded the fuse on my Uptone JS2 and it made a dramatic difference.

The Uptone is powering my Lumin U1 mini.

Is there an aftermarket power supply for the Qutest that is grounded?

Most of them are floating output voltages rather than tagging the voltage to ground / AC neutral.

But is that what you meant? Are you looking to ground the Qutest case? That is a different question.

Yes but neatly.

At the moment I just run a BNC to RCA adapter and then a iFi groundhog thing. So just a power plug with only the ground pin connected up to one of the free spots on the DAC. Works, just wondering if could do a two for one, upgrade the PSU and have grounding built in.

Hi Benno, I find this text by Nordost explains the different kinds of grounds very clearly and concisely. Seems that you are mixing the meaning of signal ground and earth ground.

Will have a read.

The gist of it is with the Qutest into a Kenzie Encore or into my active speakers (2pin power), there is a ground loop of some sort formed and savage noise. Something that happens with no other DAC yet.

If I connect any part of the Qutest such as one of the RCA or BNC ground/negative to a ground pin power plug (so powerboard, or direct to wall, earth pin to RCA/BNC ground/neg) it stops.

I'm using a Shanti with a Qutest. I read about the flimsy stock DC cables in this thread, but I'm not willing to take things apart to replace them.

Do you folks think that merely replacing the stock DC to micro-USB adapter with a Ghent Audio one (while keeping the stock DC cable intact), could make an incremental improvement? Or is that only a meaningful thing to do if the DC cable is replaced?

I doubt that changing the adapter will do much. The existing dc leads are excessively long so you could cut them down to a shorter length which will probably help much more.
