These are not vinyl rips...direct from my original SACDs. Also, they don't have any noise with my LG phone with same DAC. I'll try FLAC and mp3 when i get a chance...but something doesn't sound right.
Are you sure that your LG is not applying extra noise filters? How would you judge which one of those two sources is more honest in terms of the original track noise level? Do they have the same SNR? Same output impedance?
The thing is that it is not so easy... While comparing smartphone with DAP I would tend to trust DAP more cause it is designed to deliver the quality unaltered whereas smartphones don't have a suffucient element base for that and tend to mask out something. It is like beauty shots with your front camera. Or even back camera shots that makes more smooth skin caused by lack of resolution... Anyway, time would tell.
