Is the Monarchy DIP effective?

I now plan to use my Oppo BDP 83 as a transport to a McCormack DAC-1. Connection would be via Toslink.

Would a Monarchy DIP (not the 24/96 version) or an Audio Alchemy DTI V2.0 be worth inserting to the signal chain? Would I get any SQ benefits or would it be detrimental?
I'd be connecting the Oppo to the DIP or DTI v2 via Toslink and then connected to the DAC-1 via Digital Coax. Possibly the Black Cat Veloce from Chris Sommavigo.

Thanks everyone and advise when you can.
