A capacitor has resistance and inductance.
A resistor has capacitance and inductance.
An inductor has resistance and capacitance.
A wire has inductance.
A PCB trace has inductance.

I peruse your post diligently and regularly and without the technical ability or test equipment I can concur with the rationale of your deliberations clearly and intelligently though emotionally exposed but good education .....and also useful knowledge to my pursuit. I have by 1995 when Digital technology overwhelm AUDIO Hifi to make the 1bit player and it's convenience...clear cold clinical sound but would not accord with the musicality,  natural warm tone of the acoustic instruments that shimmers and vibrates tingling sensations and give life to music ......in the first decade of teh new century relinquish the new bright clean sounds for Proprius, Genera. Nova. But the all Important DAC has improved to reproduce through software synthetic acoustic tone ....And digital pre amp to attenuate the huge line signal. The Hifi Industry has not allowed me to fulfil my audio music development and I read and  read your blogs .......to develop what is much needed for audio enthusiast ..a True GSP or DAK tone analogue Pre Amp .....incorporating an active buffer with Valveeee...ee tone between Proprious and DAC........and somewhere in the last few pages until I can digest it is the secret ...but need a Designer committed to a DAK analogue Pre amp....with  an active op amp Buffer ...Can you help....

I can certainly help. I am trying to reach that goal. The power amp had to be achieved first because of the costs involved. The costs are difficult to explain here, but have had to follow a planned direction aimed at succeeding.
Not simple enough for Google-Bot to understand...

Without Pre-empting any your designed concept for an Analogue Pre Amp ...I can no longer resist the temptation to ask when yours|(above) posted on 21st February at 5:20 AM reached my laptop .....

Would an Isolation Transformer deal with the of Yours above in italic and isolation transformer to achieve matching inpedence between Proprious and DAC or Genera ....Please ?
