There is no such thing : a sound without "color"....An uncolored sound means nothing in an absolute sense...
All sound coming from a room, a particular house, a specific electrical grid, a particular audio system is colored in some way for some particular ears that listen to these same" colors" in their particular way and will perceive them in their own way...
Tweaks by themselves are only that: tweaks useful or not....
But controlling the mechanical, electrical and acoustical embeddings amount to more than using a tweak or 2....It need to be take care of in a systematic experimental way.....It is possible, cheap, and audible by me , my dog, and even my wife (perhaps not my wife).... :)
