I'm searching for a Dap with warm sound signature but also with touch and stable UI.
My experience until now:
Ipod touch 4g: good impact and detail but with soundstage too compressed; also little too bright for me.
Samsung s3: less detail and sometimes with grain treble, but with soundstage much wider than ipod
Fiio X3: beatifull warm sound signature, but no touch and SQ not so much higher than Ipod and S3
