Any particular track I can try out ?
I was one of the early adopters of the EPH100 and very active in the thread to share how good it was.
I don't think you will be disappointed at all with female vocals on the A73 as its mids are lush and have more detail and texture. I was listening to Sade and it was very melting and sensual at times. I also listen to Trance vocal so female vocals are also important to me.
The A73 is better sonically in every way over EPH100. It makes the EPH100 feel dated and low end budget. In fact for a long while I was in search for an IEM that had similar sound signature to the EPH100 but improved in every way - A73 is that.
A73 is what EPH200 should have been.
Just make sure to use wide bore tip and ensure you get a good seal to get the most out of its sumptuous bass.
