My system which has been a work in progress over the past 3 years has gone from good, to great to simply fantastic. However now with the addition of a PS Audio PP15 and PP12 the separation of instruments sound stage and depth is totally indescribable. My speakers have pretty much gone AWOL. 90% of the music is from the back wall from side to side, top to bottom. I think I'm done for now 😌 😅. You can see my system in my details. Thanks Paul.
