A different power supply definitely improve the THX sound quality according to my experience.
There is no noise heard with the original power supply come with THX.
But the imaging is big and not condensed.
I tried a probably poor quility 24v 0.5A LDO for other device.
cost $60

(YES I aware 0.5A is low.buy i don't believe THX consume that much
since the machine is no heat coming out
)
This improve some image issue.But bass texture was fucked up.
So I figure out the image issue comes from power supply.
I give iFi DC iPurifier2 a shot .

This stuff is some how expensive.but I am too busy to
DIY stuff recently.And this stuff is full refundable in my
place.

Finally the sound imaging condensed.just like making the focus right in photo.
But one thing must aware is iFi DC iPurifier2 gets very hot working and even with THX shutdown over night.
Probably 60~70 degrees Celsius.Might need to find transformer with switch to use with this.

In fact I am also confused to the issue I heard. Since the measurement is inaudible and near perfect.
But I have lend THX to my friend for over a week. And I didn't told him any thoughts about this amp.
It turns out that he has notice the same issue.
headphone mainly use: Z1R, A2000Z, SRH-1840, TH-X00
compared amp: Jotunheim, Gustrad H20, iFi Pro iCAN
DACs: Grace m9xx. Pioneer N70A
The issue persists with and DACs and headpones. And only with THX.
I thought THX is just tuned like this.And everyone just love it.So no one complains.
Until I go power supply change for fun as usual.
