I am always curious why people can experience same IEMs so different, my suspicion is, its the different genres we listen to. Thats why I am wondering, if anyone experienced Anni lower res than Rn6 like you did
When I comapred both, Anni was a clear winner for me. Not just in regard of resolution. But I am quickly bored by an overly safe tuning, so I know I am bit biased towards Rn6 which yes, sounded bit boring to my ear. Great IEM nevertheless, with fantastic balance, it does many things right, but I certainly wouldnt buy it.
Anni was considerably more detailed with probably best treble I ever heard in an IEM, had more remarkable treble, initimate mesmerizing mids (not Mentor or Traillii level but still very high up there) fuller bass and had very fun energetic, but none-fatiguing tuning. I still have trouble wrapping my head around how this package comes together but it does in a very unique way.
