... minimalism1
This kind of minimalism reflects itsself also in the circuits, see for example the products of Nelson Pass, Greenwall or Brain Audio (what happened to their super transistor?). They claim to use just one active amplifying part (usually a Mosfet) and very few passive parts. I'm just wondering then why you have to pay the same amount of money like for the ``parts grave'' of Mark Levinson et.al.

If you choose $k=10$ the equations turn out as
$\displaystyle R_{26}$ $\textstyle =$ $\displaystyle \frac{3180\mu s}{C_{36}}$ (2.7)
$\displaystyle R_{24}$ $\textstyle =$ $\displaystyle 0$ (2.8)
$\displaystyle R_{22}$ $\textstyle =$ $\displaystyle \frac{R_{26}}{9}$ (2.9)

which means that we can omit one precision resistor.

The voltage regulators of the phono preamplifier stage also need small heat sinks.

It is very questionable whether reflections play any role in audio applications at all. On the other hand it does not hurt to prevent them.

... distances4.1
The opposite philosophy is hold by Naim: their power supply regulation is either a simple one located in the power amplifier or an improved one within an external power supply (Flatcap, Hicap, Supercap). This allows to get higher sound quality when connecting the preamplifier to an external power supply. If the power supply regulation were located within the preamplifier then chances were high that a much better sound quality could be reached with the cheap power supply in the Naim power amplifier-but Naim would not sell that many external power supplies as well.

It is very interesting to note that the graininess of digital sources disappears for the bigger part if the preamplifier drives a better power amplifier!
