Congrats. Always great when you really enjoy your new piece of gear.
Out of curiosity though, did you mean the Eversolo Z8 instead of A8? The Z is the dedicated DAC model and the A is the full streamer unit. One uses ESS and the other AKM for its DAC configuration. Granted, they'll probably sound pretty close but the AKM is often reported (subjectively) to be slightly softer at the top end.
