Going from MV55 and Premiere 17LS to a integrated

Hello All,

I currently own a system made up of Audio Physic Virgo speakers and Conrad Johnson MV55 and Premiere 17LS preamp. I am downsizing my speakers to a two way monitor and don't wish to spend more than $3,000. Harbeth Compact 7 ES3 are under consideration. Would the Conrad Johnson be overkill? I'm thinking Naim Supernait or Nait XS. Seeking suggestions on integrated amp to run Harbeth.
