Amp for Harbeth P3ESR and Cambridge Audio Azur 851N

Hi All,

Please suggest a good amp that provides enough power and midrange for my new Harbeth P3ESR. Music source is usually from Tidal played from Cambridge Audio Azur 851N network streamer.

My speaker is in my living room about 12x15ft.

 I listen mainly to classical music, Jazz and vocal.

Thanks for your advice.


Hi All,
Anyone tried the following combination. Would like to make my decision today. I am in Dallas and that makes it so difficult to audition any of this option.

Option 1:
Harbeth P3ESR
All-in-one: Naim Uniti Atom (New unit @ $3200)

Option 2:
Harbeth P3ESR
Source: Cambridge Audio CXN V2 (new unit $850) or Azur 851N ( used unit $1,250)
Amplifier: Sugden A21SE Signature (stall demo unit, $2650)

- Which option do you think is better from audio perspective? Any of you have tried either of this options?
- Option 2 is about $600 more with a lot of used components. But seems Sugden is well regarded by many as the best SS integrated amplifier in this cost range. Is this worth the extra spent in your opinion?

I am going to put this in a small living room. And I listen to a lot of slow rock, classical music and R&B vocal and Jazz.
I have the Harbeth P3ESR and the Naim Uniti Atom and I'm quite happy with that combination. 

I have gone with option 1. Which is Naim uniti Atom + Harbeth P3ESR. I felt the sound is a little thin to my liking. It lacks lushness, power and details. I want to add amp between the uniti Atom and Harbeth.

Any recommendation?
BTW, I moved the setup to my bedroom. The sound does improved due to smaller enclosed place compared to living room. This is expected. But still something is lacking....
My P3ESRs sounded amazing with my ARC VSi55 integrated.  It ran pretty hot in the small room I had it in and I recently switched to a Vincent SV 237 integrated.  It incorporates an amp with the first 10 watts in class A with a tubed preamp and has maybe 95% of the magic of the ARC, but in spite of the Class A runs much cooler.  I'm very happy with it.  I have no experience with the other amps you mentioned, so can't compare.
