I have both dx160 and LG v35 (almost thebsame phone as V30). The sound signature is not very different, instrument placement is quite similar. Lg soundstage is little wider but soundstage of dx is clearly taller and deeper. Unlike ibasso, LG places cymbals directly in my brain which gives illussion of the smaller soundstage generally.
Dx sounds overal smoother, with more subbass, cleaner vocals and cleaner treble(much less grainy). Lg sound is little bit more hollow but somehow more punchy.
Overal difference is not huge, sound signatures are similar and the difference only matters during very critical listening. For me personally difference is worth it but to be honest I wish sound signature was little bit more different so that I could apreciate the change more.
Keep in mind that I no longer have iems and my comparision was done on Ananda, k702 and dt880.[/QUOTE
Thanks for the detailed reply. I appreciate the time you have taken for the in depth comparison.
Considering they have a very similar sound signature I might stick with the v30. I do like the sound signature and it pairs well with my fh7. It will also save me 600 AUD.
Did you use the high impedance mode on the V30?
Cheers
