Given my setup/room I “think” I am at I hope 90%+ system resolution. I have experienced profound clarity, depth and resolution with the some recordings. Others not so much. For those like Mike and many others here with what many consider Sota systems, are you now looking only for “the” recordings? I know I can upgrade more, but really, when I listen to my reference recording which is Hugh Masekela/hope/stimela on CD rendered through the digital chain in my signature, I cannot think of any upgrade I could make, other than the recording, to improve other recordings realisms. Does this make sense? I have not been in this boat before. in the most recent past upgraded equipdment/ room was the thing that provide that 15-20% improvement. Granted I have not heard very very top Wilson, Arakis, Kodo type speakers (maybe they are the “last reach”) but can they or their equipment equal/beat the truly Hi Rez(analog or digital) recording hi water mark like Hughs?
