This does not explain what you mean by “timbral intonation.”
The single page referenced in what appears to be a book briefly discusses the use of the word intonation in linguistics, with a very different proposed meaning than how we use the word in music.
I took the feet off and I use Sorbothane Feet. Whether I can hear the difference is debatable. It does sound very good.
I invented the term for classical vocals and string instruments. I did remove it though 
The linguistic explanation is gone too.
No need to remove anything!, although you are welcome to do so if you like. 
I was curious as to what you mean as I have never seen the use of the phrase, after having performed in dozens of orchestras, etc.
Dear watchdog507, can you please tell me whether the ST Blue fuse you used to replace the factory fuse was also a fast or a slow blow fuse. I’m about to replace the fuse in my 200W HDPlex linear power supply and I wonder if I can replace the default fast fuse with a slow blow tuning fuse. Thank you.
