Thanks. I see that the answer to my question about whether better equipment would make your system sound better is "yes."
Any better piece of gear will do better.... And they are plenty of pieces better than mine...
For example for my dac the Denafrips very high end will do....
For my Sansui AU 7700 the Berning ZOTL would be a bargain upgrade in ratio S.Q. /price...
For my speakers it is more difficult to pick one, but i will pick a Tannoy piece like i already own....I dont want to risk a frustration because my Mission Cyrus 781 are very good already...But a high end Tannoy will beat them with a more refine British sound...
But if i add all the cost of these upgrades around 12,000 bucks perhaps 15,000, the comparison with what i have already and what the upgrading effect will do, it is way too much money for the differences...A great difference is not a huge one.... I know what a huge difference is with my own gear BEFORE and AFTER my embeddings controls, especially the acoustical one... Acoustic is a HUGE factor....Exceeding any upgrade....This is the reason why boasting about ANY piece of gear is "naive" in audio....The gear are generally not the solution, the embeddings controls are....
I already have a piano or an orchestra filling my room.... Would i pay for an improvement which will be a real one, but not so much over what i already enjoy? NO.....
The important part of my answer is not this evidence that any well designed piece of gear could be better than mine but the fact that my embeddings controls give already to me a MINIMAL experience of the high end but also a very real flavor of the high end, this at peanuts cost........
I apologize for my lenghtly reply....I know that you dont like that.... 😊
I wish you the best there is and will be....
