@coralkong The producers job in the recording studio is to help the musician get the most out of his own talent, the engineer puts the technology together to facilitate that vision. Often the producer doesn't want some instruments to sound their best as far as what the instrument maker wanted when he made the instrument, distortion, overdriving, tape saturation all kinds of "mistakes" that were used to create art. I'm not talking about that I'm talking about what should be the the heart of any good playback system. For me I have some tube amps a tube preamp and I love the way they sound but they are not accurate because I have a mixing studio in the same room as my audiophile system. If you love the music then you sorta are committed to the way the musician and producer wanted the recording to sound the day they mixed and mastered the song. Accuracy not your preference is what I mean.
So If you take 2 channels of high end studio preamps SSL, and run it through studio standard processing Avid Pro Tools, then play them back on a speaker system at least as revealing as the studio monitors (that is easy for good audiophile speakers in general) you have a limit of quality. When we buy every expensive audiophile equipment to playback these songs we are not revealing what the musicians and producers envisioned to the point that our equipment is better than the studios we are in no-mans-land because the engineer and the producer haven't heard the things in the original recording that we have and that is also inaccurate.
Also Abby Road Studios uses lots of audiophile equipment because they make a lot of money from it, product placement is the name for it in the industry. Speakers are the things that can be the most problematic I only mentioned the Bluehorn speakers because they use newest tech.
