IS the AM3D a big upgrad in terms of sound quality compared to the AM3A on the X7II ?
While the original AM3A has its merits, the. AM3D provides a different aspect of sound quality, as shared in the review, the low noise level of the AM3D provided for a darker background allowing the THX amplifier circuit to do its magic. The module has been sold out many times over and the current batch is likely to be the last batch as shared by FiiO CEO James Chung.
