I have 6ks and upgraded my 818v2 to v3 and felt it was a very worthwhile upgrade at a relatively modest cost. I posted at the time my system sounded the best it ever had and I still feel that way.

However I find it difficult to hear the difference between a well recorded 96/24 track and the same on MQA. Case in point, when comparing the 2L MQA and 96/24 downloads I'm hard pressed to hear a difference. I think this is a limitation of legacy DSPs rather than the 818v3 and I suspect very good analogue speakers through an 818v3 would have a leg up on legacy DSPs.

I had a brief conversation with Bob Stuart at Newport Beach last year and I asked how MQA would sound through legacy DSPs and his answer was the sound would be equal to the very best source available with legacy DSPs, or words to that effect. Clearly MQA and one of my best recordings are at least equal on my system now so if that's what we have to look forward to with the 818v3 and legacy DSPs when more MQA becomes available, well that's not too shabby.
