DCS Vivaldi stacks vs Esoteric Grandioso G1, D1, P1 stacks

Hey all,
For my digital front end source components I am currently using the DCS Vivaldi stacks which include : Vivaldi master clock/streamer unit, Vivaldi upsampler unit, Vivaldi DAC unit, Vivaldi CD/SACD transport unit. They sound and perform phenomenally well and have great sonic synergy with the rest of my equipments. 

But I'm thinking to make a switch to the Esoteric Grandioso stacks : G1 master clock, D1 monoblock DAC, P1 CD/SACD transport, to see how these Esoteric would stack up against my DCS Vivaldi stacks in my system. I'm using the Dan D'Agostino Momentum analog linestage stereo preamp and the Dan D'Agostino Momentum M400 monoblock amps (2 pairs) in bridge mode. My speakers are Wilson Audio Alexx. Speaker cables, interconnects and power cables are Transparent Opus. 

Has anyone get to compare the DCS Vivaldi stacks up against the Esoteric Grandioso stacks? 
I would be eager to find out how the Esoteric Grandioso stacks would sound in my setup especially in direct comparison to my existing DCS Vivaldi stacks. We don't have a single Esoteric dealer in our area so I have no way to demo the Esoteric Grandioso especially in the same setup as the one I have at home. I would love to give the Esoteric Grandioso stacks a try in my own setup at home. I've read nothing but outstanding reviews on the Esoteric Grandioso stacks, so I thought I might want to give them a shot. The Grandioso D1 DAC is monoblock configuration. 

Your advise, inputs and opinions will be much appreciated. Thanks in advance.
