Upgrading from Integrated Amp to Separates


I have a Primaluna Dialogue Premium HP integrated amp now, driving Harbeth M40.1's.
I like the sound, but am considering upgrading to something more powerful and with greater finesse.
I have had solid state gear in the past and have always come back to tubes, so I think I want to stay with tubes.
I would like to get a stereo amp (no monoblocks) and match it to a very nice preamp.
I have been considering Balanced Audio Technology gear but beyond that I really don't know.
For my budget, I would prefer not to go over $10K total for both components.
I am in no hurry to make this change, just thinking and doing research right now.  I am willing to take more than a year to decide if necessary.  
Please give me your suggestions.
Thanks!

Check out Modwright, also I would consider a excellent McIntosh MC275 tube amp with a Mcintosh C22 preamp. This combo with the Harbeths would be a match made in heaven.....call Audio Classics for mac gear.

Look into the Lyngdorf 3400.  Brand new model. I have the older 2170.  I used it on the 40.1s.  Amazing together. Sell your dac, power cord and ICs as you won’t need them. The room correction in the 3400 is stunning and SOTA. I sold over $18,000 of tube separates and like the 2170 better. The 3400 is even better. This piece will assure the 40.1s sound as the builder intended in your room. I know this is not conventional high end advice. This is not a conventional piece and it breaks all manner of aphile notions and perceptions. No worries regarding tubes as this unit transcends that whole SS vs. tube thing. Just is beyond that. It sounds like music and your room will no longer be against you. It eliminates the room. 

I speak all this based on vast experience. I know, this is not what you wanted based on the subject, but I sense you may welcome it. Enjoy. 
I have the PL Dialogue Premium and went to BAT separates. VK55 amp and VK31SE preamp with great results. Yes they are older but sound fantastic. With your budget I'm sure you can get better.  Grannyring brings up a good suggestion also.  I know another Audiogoner went this Lyngdorf route and is really happy with his choice.  
Another popular choice with the Harbeth speakers are the Luxman integrated amps.
