I have been using the Stereo Setup feature now for a couple of days and I must say this is a fantastic feature. It sounds way better than doing the same thing in the analog domain with my Benchmark HPA4 preamp. Only issue is that I get this benefit only with my streaming, not with my turner which I use from 9AM - 12PM M-F.
You will notice how powerful ROON is if you have multiple zones and also use headphones. Adding convolution filters to specific endpoint also takes the complexity up a lot. It all works great, but I removed my Convolution filters after getting different gear.
Using a Convolution filter would have also resolved my Balance issue but that is incredibly complicated to do correctly, and I only get a professional to create those filters. I used this guy in the past.
