I am afraid there is no odds here...Or odds are not enough which is what the OP think about....
Like buying a house or a car, buying an audio system ask less for odds than for a minimalistic search for knowledge and experience....
There is no "taste" also in good sound or in bad sound....There exist variations between systems tough,but variations are not reflective of some predetermined taste first but reflect more the many differences in systems with their embeddings dimensions....Instead of taste i prefer to speak about different perspective in sound presentation and interpretation....It is often "habits" disguised in taste....😁
We must all learn to listen... Listening experiments and experience are our personal journey and personal history...It is true for sound quality and it is true for music... Nobody is born with an immediate expertise in S.Q. acoustic nor with the irrepressible taste for Scriabin....All that is learned ....😎
A good natural timbre of an instrument is easily audible modulo a minimal experience in the listener...
Bad imaging is audible....
Harshness, or warmness, compressed soundstage, poor dynamic are all audible facts...
No tastes here....Only habits veiling or hiding limitations...
I discovered how to improve controls in mechanical electrical and acoustical dimensions where any system is embedded...It was an adventure in thinking, reading, and experimenting and funny, very rewarding....
It is the ONLY road i know....Please explain to me if there is another one, i will listen to you...But beware, my road had cost me peanuts...Costly solutions are NOT solution in my world....Anybody owning the money already can pay 500,000 bucks for a good system, no great challenge here.... It is more difficult to reach great results with 500 bucks for a system and peanuts for the embeddings controls devices.....😁
Then this is the road for me and the rest is most of the times costly upgrades...
But almost all good system, even costly one, need less an upgrade than a good embeddings controls, that is a fact....
When is good good enough? YMMV.
You answered yourself.... When you listen music without thinking too much about upgrade this is it....
All the rest is hobbying or obsessing.... We have the choice....
My best to you mapman....
