I don't know any individual that is a Tube Lover.
I do know individuals who have come to the conclusion that a HiFi System with devices built with Tube Circuits have found a device that is deeply satisfying and is a preferred experience over other experiences.
This can be discovered through the use of an individual device such as a Phonostage, DAC, Pre-Amp', Power Amp'. It is also available through a combination of Valve devices used. In many cases the combination is produced as Hybrid, being SS and Valve Devices to produce the System.
Those who take seriously finding a presentation from a system, to be one that is totally satisfying and able to deliver to their unique preferences are willing to take steps to increase experiences of differing permutations of available equipment.
Very few do any Math whilst on this journey, they are use their senses and stimulation created to settle the outcome of a assessment.
I am fortunate to have still have an interest in Live Music and on many occasions, can be at a close proximity to a performance, never ever have I used this type of encounter to make a decision on a Tube vs SS Circuitry as being the superior, even if a see a Valve Amp in use, along with SS Instrumental Equipment. Never ever have I heard this as requirement to make such a assessment.
I was out of this thread, but such a huge BS Statement is not of any value in this thread.
If one wants to talk about a Bass Notes Impact at a Live Performance being quite different from a Bass Note Impact produced by a Home System, then there is plenty to 'chew the cud' about.
