Most hobbyists will not be in the class of systems to enable all genres and recordings to sound wonderful. No judgment of anyone’s efforts, just experience with gear from budget to close to SOTA.You seems to be serious?
I had an audio system that cost me 500 dollars including dac, amp, and speakers, and it is the best sound i ever listen to.... Why because it is not the price of the gear that impact most but the way it is embed in electrical, mechanical, and acoustical dimension...All genre sound marvellous here even metal or acoustic....
And beside that one of the best amplifier in the world in 1978 does not becomes automatically scrap today...
If your job is selling gear it is ok, but it is a bit snobbery to allegue price to be judge of the way a system sound without being even conscious of the acoustic extraordinary impact.... I dont even mention mechanical and electrical embedding, i doubt you even know what it is....
Sorry to be rude....Awake to reality ans spend less on electronics.. Spend more on thinking... :)
Audiophile experience is not reserved to 100, 000 dollars system....
mine is so good upgrading seems ridiculous....There is better yes, but by a small margin at very, very, high price...
Embeddings: the multiple ways a piece of electronic components is connected and immersed in system gear, house, and room....
To your discharge most audio system dont sound at all with their potential S.Q. it is true... Because like you, most people ignore the method to embed their gear....They think that all is ok ready out of the box....And manufacturer dont have interest to enlighten them when they pay for the "best" and dont want, in addition to paying big money, any hard work to reach the high level their gear is able to reach....ANY gear need to be embed never mind the price.....
My best to you....
