My mistake. Thought you were insinuating that all amps will hiss which is not the case at all. If anything the amps you are using now are not suitable for sensitive IEMs. Have you ever considered maybe selling one of them and getting a portable amp that is compatible with IEMs?
I'm also looking forward to the 901. If it is bug free and sounds as good if not better than the DX100 I'll be getting it. Still I highly doubt the 901 will sound "much" better than the DX100, possibly better yes but that remains to be seen. But if ibasso manages to get their act together and fix the remaining UI issues I'll stay on the ibasso side.
