A individual who I am in close contact with, has a Design for a Tonearm and Phonostage, which has steadily produced others through impression made to have adopted the Design and replace other owned equipment, as the result.
Through their duration of producing the Tonearm and more recently the Phon', the individual has changed Speaker Models on Three Occasions, as the Speakers in use on Two Occasions, even though quite capable, have not been able to present all that is on offer from the Designs being put into use.
It is also quite interesting that on other forums where there is a occasional discussion about this individuals work, that some who post that have adopted the Designs, have also made it known it has taken a exchange of Speaker to fully realise what they have bought into.
The Speaker is way up in the ranking as a Tool of Importance. It is certainly beneficial as an indicator that there is an optimisation of the unification of a Mechanical, Geometric and Electronic interaction at the Front End is in place.
The Speaker is the Tool that enables the audible experience to be encountered, all that occurs prior to the Speaker carrying out its role, is just a preparation for the Speaker to produce Sound and enable a Judgement of the Quality of the Sound being produced.
The more unadulterated and correct the Sound seems to an individual, the easier it is for the individual to make a subjective assessment of what they believe is a contributing factor from upstream to the impression being made.
As a HiFi enthusiast, I am a listener of a recorded medium produced to become sound, I am not a observer of a selected assembly of parts functioning.
As a individual wanting to listen, knowing there are disciplines required to optimise the function of the assembly of parts to get a improved sound is beneficial. Practicing the disciplines to create a optimised function and adopting parts to improve the optimisation is also undoubtedly beneficial.
There is no point having the ideal tools in a kit, and then only conceal their real capabilities, as one does not know how to use them and extract their full potential.
Even worse if one Tool is believed to be the only Tool required.
