I would concentrate on the sound characteristics of the DAC and not the technology. Denfrips are highly regarded DACs for their price. I’ll let someone else chime in on the contrasting the two.
solid advice above from @ghdprentice
the op did not mention the rest of his system nor what his/her desire is for the sonic balance of the new dac being considered
the dena pontus is rather warm/rich but spacious sounding dac
just by the notion of the mcintosh gear mentioned in the op, i would think this may well be duplicative of the sound signature already being presented in the system
thusly, perhaps the op would benefit from a clearer, more upfront, livelier presentation -- which could be afforded by a chord dac (qutest or hugo tt2), an original schiit yggy, or a gustard r26 (which incidentally has an onboard streamer).... further up the price ladder, dacs from weiss or bricasti would also fit this bill
