I'm now doing just this, and using a power amp that is the complete opposite of the usual Naim amp such as a NAP250.
I use a Luminance KST-150, which is a high bandwidth, high slew rate, very fast and neutral amp. Pairs very well with the 272 using its RCA outputs and sounds excellent. This amp has a 20k ohm input impedance and does not like tube pre-amps, but works perfectly with this Naim.
The 272 does respond highly to quality isolation footers such as Stillpoints or Cerabase, or a recent cheaper option I just tried, Stack Audio AUVA EQ.
