I am thinking to put the XLR-RCA adopter as temporary solution.Keep in mind that doing this is likely to have considerably greater sonic consequences than those caused by the adapter itself. By changing the cabling from XLR to RCA (if I understand correctly that doing that is what you are referring to), in addition to the cable change itself you will be changing the configuration of the interface circuit that is being used in the component driving the cable, you will be defeating the advantages balanced connections provide with respect to reduced susceptibility to ground loop issues and noise pickup, and you will be reducing overall system gain by 6 db.
If you do want to use an adapter, you might find that better results can be obtained by connecting an XLR male-to-male adapter in series with an XLR female-to-female adapter, which would avoid those potential downsides of using an XLR-to-RCA adapter. Of course, not using an adapter at all would still be preferable.
