It is a bit philosophically " naïve" to think that audio components has a sound of their own out of the continuous participating acoustic space of a room and that we can predict how they will sound without the specifics of any particular room and out of any particular electrical grid, and out of any resonant particularities of the audio grid and room...
Each component has his own particularity electronically speaking, but the end result of all the system in a particular complex embeddings is the truth of the system for the ears not his design only....
Example: an ordinary audio system in a perfect acoustical environment will be better than a TOTL in a poor room, without acoustical treatment, nor vibrations controls, with a noisy electrical grid, is it not evident?
P.S. salutations to Geoffkait , I think I miss Glupson also... :)
