Good to see you posting again. I would consider a Conrad Johnson pre-amp.

Keep me posted.

Happy Listening!

If you are seriously thinking of changing speakers I would do that first, then adjust your components to optimize the sound quality for the speakers. Then do cables and powercords.

I would absolutely look at the Backert Labs Rhumba Extreme preamp as being a great match for that amp.  Contrary to jafant's suggestion,  I would steer clear of c-j preamps - their output impedance curves are all over the place with changes in volume and the big McCormack works best with XLR inputs anyway.
