I won’t comment on this subject for those with unlimited budgets or a $100,000 budget ceiling. It’s clear that any upgrade must be defined by the overall synergy of the elements involved and their integration within a specific room, considering its acoustic properties and content and for a definite budget with all pieces with a comparative proportional price.
Every upgrade must have a general goal: the integration of an element into an acoustic whole. Therefore, changing an element without knowing how to optimize it for optimal integration within the overall acoustic environment and the synergy of all participating designs is a mistake, even if the upgrade proves positive.
A difference is not often really an improvement if its significance in relation to the total acoustic experience is not understood.
Upgrading is a dead end and often a pointless expense if we don’t understand the source of our acoustic dissatisfaction and its underlying cause.
Upgrading is a dead end if you don’t learn the basics of the system optimization process, regardless of the price of the system pieces...
Upgrading often reflects our ignorance of a fundamental fact: there is a huge difference between a system and its acoustic environment before and after optimization.
Before upgrading a piece you dim obsolete or not working well or unsufficient you must optimize it and the system also...
The optimization process—mechanical, electrical, acoustic, or DSP-based—generally costs less than an upgrade, and even if it does cost the same, once implemented, it provides a satisfaction that reveals the absurdity of throwing money away, when we are influenced by marketing instead of basic knowledge. As i said there is no comparison between the same piece or the same system working at his peak potential after optimization or right out of the box without optimization...
I call the state of being happy with the least possible costing system/room with no frustration of any kind in spite of the limits of a specific system for specific needs (mine is for nearfield and optimized for a small acoustic corner) the "minimal acoustical satisfaction threshold or MAST.
Once there you smile and laugh because of the low cost /S.Q. ratio.... You quit upgrade and marketing because you have learned minimal acoustics basic......
