I think technically every penny you spend on gear after getting something that lets you enjoy music puts you deeper and deeper into diminishing returns territory. So the best audio system in terms of SQ/price is the cheapest gear you enjoyed. Which is clearly going to be different for everybody. I personally would be content with any of the headphones I have (HD600, DT770, K545), which is why I have them in the first place.
Very good answer in my book...
Anyway my question make sense in this audio forum, if we want together discuss and detail for our readers what are the qualities of the basic components which for us represent this threshold of optimal S.Q./ price ratio for musical satisfaction...
For me i am astounded that after the optimization of my headphone ( K340 ) for the first time of my life i enjoy music without being bothered by the limitations of my actual system precisely because these limitations so much less audible than on my past others multiples components are now no more bothering...
The lesson i learned is that it is way more difficult to stumble upon a very good headphone nowadays than on a good amplifier or even on a good dac... ( None of my past headphones gives me any satisfaction at all compared to my speakers/dedicated acoustic room )
My dac for example is a basic one and in spite of that, the music coming from my hyeadphone amaze me non stop from the moment i finalized his optimization.... I dont really need now a new "better" dac or a new "better" amplifier... But by God! i needed badly this headphone K340 , thanks to God i have it, i could no more fault my audio system, not because it is perfect, it is not, but his limitations are no more a sensible audible impediment.... This is the reason i thought so highly about this headphone....
My thread is about what others experienced similar to mine, relative to this threshold you spoke about wisely , or related to this S.Q. /price optimal ratio which is a factor necessary to "compute" in any wise purchase....
As i said there is no absolute best component, but there exist the best possible for our joy and ectasy.... It would help others if those ,who are like me or like you in audio heaven, communicate how, and why and with what components they are totally happy ....
A question: what is different in these 3 headphones,(HD600, DT770, K545) and why and how could you be happy with only one of them ? Myself none of my past 9 headphones make me happy... In my book it take one, the one without too much evident lacks or faults, the one with something unique no ?
Thanks for your participation and my very best to you....
