Building second system around Harbeth P3 esr


I bought the P3's a couple of months ago. I should have some cash soon to go forward with this system. My thoughts are the Croft Phono Integrated. Please share your thoughts on not only the amp choice, but what this systems strengths might be. I just want to listen at low to moderate levels, and be engaged. I wish they were more efficient, which is why I'm thinking Croft, which has a tubed stage, and SS amp.

Thanks all. I may give Gene a call, but will first seek out a closer dealer. 
With regard to a cartridge, I have some time to figure that out. I would like to avoid an SUT, and the extra cable that would be needed. So either an MM, or a High output MC.  I want to play to the strengths of the system. What I mean is a nice refined, fleshed out midrange. 
I am setting up my office system as I write this.  I bought a pair of P3ESR used ($1200) and went with the Rega Brio-R, DAC-R, and Apollo-R (I got all three new for less than $2000).  I had Mike at Audiophile Vibration Control build me a desktop stand for the components.
Another recommendation for Gene Rubin. Very personal, helpful, and professional. I have purchased from him more than once. Satisfied every time. 
miner42- Very nice office system you've set up there. If I was going to set up a digital based system, I may have taken the same route.  What I plan to do is integrate this system in to my main listening room. It will be for shorter listening sessions, when I don't want to play the main rig. The benefit there is I can use my Well Tempered GTA. In the future, I may try this in the bedroom, but I'm thinking playing vinyl in the bedroom may be a little over the top. Please update us when your Rega/Harbeth system has some time on it.
You may also contact Michael at Blue Jay Audio. (It’s me). Anyway, I find that the best synergistic match with the P3ESR is the Exposure 2010s2. In my opinion it surpasses all the other usual suspects. Naim, Rega, LFD, Leben, Luxman are all excellent matches but the Exposure is the ideal compliment in my opinion.
