Upgrading from Primaluna

Recently went down the front end upgrade path and am running a nice table and phono now. I'm curious as to what the weaker link in my system is between my Primaluna Dialogue Premium Preamp and my Dialogue Premium Hp Power Amp. I'm considering swapping out the amp to a Ps Audio BHK250 for the summer to avoid heat, but am curious if I would be better off dealing with the heat and moving up to say an Allnic L-7000/Arc Ref 3 for the Pre. I'm happy with tubes on the front end, but curious if I'm running out of gas with 88DB efficient speakers and a single chassis tube amp. Which amp would you upgrade first and what benefits would you expect?

2 ft from the side walls sound correct. However, that measurement should be from the tweeter or center of the speaker...not taken from the outside edge of the speaker. 

And yes, do add diffusion/absorption on the front wall and look at the ceiling as well. These will make the speakers 'see' your room as bigger.

Think of the front 1/3 of the space as the highest priority to 'soften' and diffuse.

I had my Evo 400 running my old 88db 6ohm Salk speakers on the 4ohm taps for years before I tried the 8ohm taps for kicks. Upper treble and mids were much better with 8ohm taps with no adverse response from the bass. I could have kicked myself. I assumed because the Salks dip to 3ohms that the 4ohm taps were the way to go.
