Spdif source switching?

Right now I have a modified Xindak DAC 5 from Exemplar. Would adding an extra device to my system just to gain the extra inputs be a better solution than getting a different DAC? Right now I am auditioning an NAD M51 on loan from a friend and so far I like the sound along with the idea of having DAC/Preamp in one component. I'm also interested in the Musical Fidelity M1 Clic. Do you guys feel this might be a step in the wrong direction? The rest of my system is Tube Audio Design amp and pre. Thanks a lot for all the suggestions.

Why not consider using a combination of the Audio Authority 1177A-1 alongside a Monarchy DIP or if budget allows an Empirical SM. This would allow for up to 4 digital inputs (coax or optical or a combination of both) with auto or manual input sensing, whilst also addressing the issue of jitter.

I have a great DAC -DCS Debussy which does not have toslink input
I use a cheap toslink to spdif converter and I am looking for an upgrade with a better sound.
Audio authority,monarchy audio ,synchro mesh or something else?

Apparently, the new MQA would not work with the Synchro-Mesh as MQA needs everything to be bit perfect.
