Back to the question..
NO
I believe the technology is there to be able to reproduce music with good Fidelity , low distortion, Wide FR. Linear dynamic reproduction. We know now more about the interaction of room and speakers than we did 20 years ago and we now have enough computing power to do some decent Room Correction without necessitating a multi-thousands dollars processor. Acourate at <$500 or Dirac will see to that. So we can. We have the tools.
Availability of tools do not imply knowledge though. Good results requires knowledge. Whether empirical or scientific + empirical. I would think it would be rather difficult to just take a catalog and order something that will sound good automatically. There are perhaps exceptions : Beolabs, Kii, etc even those require you to know how to set up and what settings will provide good/adequate/desired/preferred results. A dealer can help. His/Her ethics can help. I am not advocating a saint, just a person who is willing to provide good services at a price that the customer agrees to. There are some.
Purchasing the greatest tech or gears or the most expensive gears is no guarantee of success. Set-up plays a large role in the final results at this point in time. Set up is not an accident it is the execution of a plan. Planning is based on knowledge.
So NO you can't
