There is a pursuit for Transparency, I am familiar with that very pursuit, and got off the Bus, where I found the levels I like.
My selections of SUT and Head Amp' are tools that enable my selected levels of Tolerable Transparency to not be noticeably encroached upon. For myself both perceptions locked onto, a very loose, slow to decay Bass, as well as the Perception of Crystalline Transparency are Detractors in equal measure.
It is also an interesting point, that the few individuals I know that created what I will refer to as a s Crystalline Transparency, spent quite a period of time attempting to discover a Rich Tone that could be added that was tolerable to themselves, enabling the periods of listening to be accepted for longer periods.
The individual on their pursuit for Transparency/Richness have to find their own unique place to get of the Bus when it comes to end sound being produced,
Too much Transparency can be well Too much Transparency, this is not a Goal in how a Audio End Sound is to be presented, it is a Idealism, a Fantastical Place.
Only a few promote the idea of Transparency, each individual should decide on their own interpretation through listening and deciding what is now 'Too much Transparency'
As Transparency is broadly described as a condition where unwanted residuals are processed and removed, as an attempt to keep the system as pure as possible. The image might help with a visualisation of what can be classed by some as needing 'Further Transparency' maybe the Grey Connector is too much colour to be able to visualise for a few. Another Group, will view this Clarity as 'Too much Transparency' , maybe a little more opaqueness to the material will be welcomed, or the addition of a translucent veil might suffice, maybe some might not want to visualise it at all, and put something in place to screen it off.
