SMSL Sanskrit 10th DAC powerd and not

[Aztk]

Hi all, I have SMSL Sanskrit 10th DAC fed by Raspberry Pi with moode audio and attached to a Luxman LV-113 amp on the other side.
I've seen the information that the DAC performs better when additionally powered, so I have a 5v 1.5A additional power in.

The strange thing is that my ears tell me the DAC produces too much bass when additionally powered. it seems not the case without additional power.
The speakers might not be optimal for a bookshelf and a small room - 4ohm speaker and a bit bigger.

Do you have some similar experience and what might be the reason?
Maybe a particular PCM filter I should be using or else?

Depends the v1 of the DAC was measured to have bad performance when running without aux power : https://www.audiosciencereview.com/...-measurements-of-smsl-sanskrit-10th-dac.5702/

v2 on the other hand didn't show any difference with or without : https://www.audiosciencereview.com/...ds/smsl-sanskrit-10th-mk-ii-dac-review.12148/

Maybe what you're hearing is the filters?

Hm... Might be, ears are not precise measurement device and there are many factors involved.
The filters add another layer of complexity and I am not sure what these are good for... I'll experiment.
Strange though, I see now I have listened to the different filters and stopped to FL 5 (Super Slow Roll-off) as the one which doesn't bothers me purely auditory.
Thanks for the links!
