I don't miss any accuracy in my tube amplifiers, quite the opposite. I also have no problem with S/N, I can go with my ear to the loudspeaker, there is silence without signal.
For me it is fascinating what excellent results can be achieved with ancient triodes that date back to the very first sound film amplifiers a hundred years ago.
I have demonstrated this more than once e.g. by giving concerts for loudspeakers. On the picture that was in France @ CARMEN - Centre Alsacien de Recherche pour une Musique Electronique Nouvelle.
Well sure, Many audiophiles, here as well, obsess about measurable difference that are aren't likely to be heard under normal listening conditions. Or they just want the 'comfort' of 'knowing' that their gear has stellar measurements, whether they can hear them or not.
