RV- With respect, and I am not being argumentative, but many of your posts on system and recording sound quality have a common theme…questioning or becoming dissatisfied with sound quality after a period of time of enjoyment and the struggle of falling into a critical listening mode rather than a musical enjoyment mode. I assume most audiophiles have the same struggle since it just seems to be a struggle imbedded in the foundation of this hobby. I will not make assumptions further but speak of myself.
I love the music. I am not formally trained on music outside of middle and high school orchestra and band (bass). I have near perfect pitch. I can hear a song once and pick out the melody on a piano and build cords even though not trained, but technique is awful. I am self read on composers and their differences in structure and technique. Combining this, I hear the difference between an 5th and an 9th. I understand the emotion a well structured pause of silence can bring as well as an allegro, forte flurry. All of this gives me the ability to fall deep into the appreciation of differences in composition and performance. I am in musical appreciation mode 90% of the time as previously stated.
I have also trained myself to turn on a critical listening mode to analyze equipment. If this mode surfaces unwanted, and I cannot go into musical appreciation mode, like @audphile1, I stop listening.
If you have not read on physiological theories regarding satisfaction and dissatisfaction, please research peer reviewed articles on hedonic adaptation, the novelty effect, and the expectation reality gap. I have found understanding how the mind works theoretically has helped me stay in musical apperception mode. While it is difficult, understanding this has helped me try to avoid the temptation and trap of constantly seeking improvement just because the initial excitement has faded, the special feeling of new is now old, or some other minor imperfection I have lived with now is a focus of mind.
To that end, when I do go into critical listening mode to determine if I want to upgrade, and I do not upgrade often, I find setting a specific goal for a defined improvement helps me focus, and usually ends in satisfaction with the status quo rather than a spend.
I know your system’s components. You have a very musical system. You post mostly on well engineered recordings. Enjoy the music. Hope my explanation of what I do helps you stay in musical apperception mode.
