Amp for Harbeth P3ESR and Cambridge Audio Azur 851N

i found LFD NCSE II integrated Amp at $8k for a used unit.

My budget is $1-1.5k for a used unit.

Which is better to drive a Harbeth P3ESR? SS or tube amp? or integrated?

I second the Rogue integrated amp, I believe they now use kt100 tubes which is what is in my Rogue st100 power amp that drive my P3's. However if you go the tube route be prepared to replace the preamp tubes with nos tubes. I run Mullard and tectronix(rca) in both my amp and preamp, the British speakers seem to go good with the warmth of the mullards. Another benefit to tubes is if you don't like the sound just replace the tubes, with SS equipment the sound is the sound and your kinda stuck with it. And by the way the p3's are glorious!

Rogue Sphinx 2 or Cronus magnum 2 ?  Which is more suitable to drive the Harbeth?

I had the Harbeth C7ES3 with a Rogue Cronus Magnum II and the combination was excellent.  The CM II should work well with the P3s.  The Sphinx should also sound very good but not close to the sound quality of the CM II.
