Well, tube rolling or cable selection does not involve the phase shifts that are inevitable with conventional analogue tone controls.
The first preamps without tone controls that I recall being introduced on the domestic market were in around 1975. Certainly by Naim Audio here in the UK. I remember having a conversation with their CEO and designer Julian Vereker at this time. Aside from the phase problems he also mentioned effects on what I guess would be described as impulse response. In 1975 we were all listening to vinyl. Impaired impulse response made ticks and scratches far more annoying. I certainly recall that moving from my Quad preamp with its tone controls to a Naim 12s without them reduced the subjective intrusiveness of ticks and pops.
Julian was not against tone controls per se. He said that he would fit them if he knew how to make them without the deleterious side effects. Now we are in the digital world and tone controls can be reinstated without the problems.
Its funny how when I had tone controls I needed to use them. When I did not the need for their use never occurred to me again!
