The CIA VDA-2 is an external DAC with a matching upgraded power supply the VAC-1. It is a SS DAC with a mild roll off filter that is analog-like. But if you ask me, my tube buffers help more with that analog sound in my system. I have no doubt that your modded Denon sounds very analog-like. Having heard the APL Hi-Fi modded Denon 3910 with tube output stage and the $25K modded Esoteric UX-1 by the same company, digital sources have come a long way to compete with vinyl. The new Marantz makes my system sound and look better!
