External Linear Power Supplies

Does anyone have any experience in comparing the following external linear power supplies:
SBooster (most expensive)
Small Green Computet
iFi Power Supplies (least expensive) ?

I am interested in effectiveness, and bang for the buck.

I would use one of these to Power a Chord Qutest, a SugarCube SC-2 and a Massdrop THX AAA Headphone amp.

Thanks.

yup, linear power supplies have a break in period just like any other electronics.  It would be anywhere from 100-300 hours based on your system and listening preferences.

Don’t know if it was break in or me adjusting to the sound but everything is sounding cleaner and more dynamic now! That’s with a linear power supply on my DAC. Does anyone know if I would get benefit out of a linear power supply on my tube buffer which sits between the DAC and power amp?

Sorry to gate crash but does anybody know of a unit that will provide dual 18volt outputs?
Each unit is only 500ma.
Or could be two separate 18vdc lps units if a dual unit does not exist.

Thx!

searching, here's one that has 2 18V outputs.  It's a variation of the LKS 25W power supply.  It really is only one power supply with two output.

Otherwise, this might be overkill, but this Zerozone has two independent power supplies that you can custom request be 18V each:

Not sure if there are others that are better.

Thx Auxinput.

I must be getting worse on my search terms for eBay as I could only find industrial and lab power supplies.
Not that there is anything wrong with those of course.
