At the shop i was listening to the dx150 with the amp6.
At first listen it was fantastic. Warmish very very smooth and lush mids. The treble is very airy and there were no sibilant and the high hats sounded clean and natural. Decays are very nice also but as many have mentioned, it sounded very close to the original dx100.
Bass was good but imo its sub bass presence could be better, it lacks the satisying decay after each bass hit.
Vocals are fantastic, very lush and full. It can be said to be one of the most reference sounding vocals for a dap, with almost little to no coloration to the vocals.
However, even though dx150 was that good, when i decided to test the dx200 with the stock amp1, my opinions to want the dx150 vanished completed hahha. DX200 is that impressive! The treble is way my style. It is definitely more trebly then the dx150 but it was not sibilant at all, it has this delightful sparkle at the high treble which gives instruments and vocals the extra oooohmp factor which i like.
Vocals are so much cleaner and brighter then the dx150 too. Vocals sounded more raw and lifelike, it is not as reference sounding as the dx150 were, as it provided some coloration to the vocals. To describe how vocals on dx200 sound like, it will be like attending a life concert with the singer singing live instead of having those studio equipment EQing their voices. Vocals are filled with emotion and simply gorgeous. DX150's vocals however indeed sounded like a studio recording.
Bass response is more satisfying for the dx200 too. The bass are airy and decay very naturally.
Soundstage wise.... Dx200 wins hands down obviously hahaha.
That's the reason why i ended up with the dx200 after that fateful day of actually wanting to buy the dx150
.
DX150 vocals sounded clean and faithful, but a bit dry to me vs. the DX200 which sounded richer and more live.
. Now, I worry, based on what you stated !
