I have a NAP 250, and it most definitely can NOT be run from the preamp.
In the olive series and the black series, these power amps can power a preamp:
90, 140, 150, 180, 200
These power amps can't power a preamp:
250, 300, 500
Even when I was using a 62/90, adding a hicap made a huge difference. It's nice to know you can save some money when you're getting started, but you really should consider a hicap as one of the first upgrades to a Naim system.
