Straight up I'm not trolling here. For the past year I have worked scrubbing the audio signal in my electronics ie preamp,amplifiers,dac,transport,electronic crossover,ect. I have not touched my speakers since 1990 and they are custom dynAudio towers. I also have 2 large subwoofers. I have gained a boatload of resolution (clarity). My question is asked because if I play a living Stereo or Columbia Mastersound or a DG recording done in the late 1950's...60's or 70's the resolution is not any less than a current recording. They have all the Dynamics,Tonality,clarity,PRAT or any other descriptor you can choose. I can hear the players turn pages,seats creaking and conductors moving. So if the recording equipment and microphones had that level of resolving power using paper and oil capacitors and carbon resistors,a long with so called vintage transformers and belden cable.... What's really changed? What did recording engineers do in their systems that we at home don't do in our systems? Btw I posted this here rather then many high end industry biased forums...This forum has always had a good mix of people who are knowledgeable and love music. Thanks in advance.
