I have just replaced a Nap 150 amp with Nap 200, for a second system. Would it be advantageous to add a spare Flatcap 2 ,that I have to provide power to the 202 pre, as I think that the Nap 200 only has a single rail supply, compared to the Flatcap 2 dual supply rails. I know the obvious answer is try it and see, but would the 200 be providing a better regulated supply overall ?.
