Matching pre-amp with Pass Aleph 30

I am currently using a Plinius 8100 as a pre-amp to the superb Aleph 30. I'm looking for more magic in the mid-range and better bass. However, I'm most worried about the bloominess that is often associated with tube amps. My speakers are the ProAc Tablette 50 Signature which most people claim should go with tubes.

Now the concern is that the impedance of Aleph 30 is 47Kohm and most tube pre-amps need at least 50Kohm for a good match.

So, I'm at a loss. Will I be stuck with a solid state pre-amp? Or rather, can anyone advise me on a good matching tube pre-amp?

Unless you're using extremely long interconnects or interconnects with unusually high capacitance the difference between 47K and 50K won't be important.

Have you considered a Pass preamp (Aleph or X series)? I'm using an X 0.2 with a pair of Aleph 1.2s, and the synergy is great. Mids and bass are quite good, and I've lost my interest in moving to tubes for the moment.

I was recommended First Sound Presence deluxe pre-amp but I'm not been very succesful in getting reviews on the net. Any one has any experience with this pre-amp?
