Since you have tried various speaker placement and the brightness is still prevalent, it's down to the electronics. The synergy between your speakers and the Musical Fidelity amp, in my opinion and some others, is the culprit. You can of course try wires since they are the cheapest solution, but if you could get someone to loan you a Krell or McCormack amp(noticed a few users who drive the Andra with Krell FPB's) then the much better since you would then be able to know how your speakers would interact with the right electronics, or vice versa. You can check out users who have similiar speakers here in their virtual systems and get some opinions from them.
I was in a dilemma once as there was a mismatch between my amp and speakers, and I have to choose which one to go despite my initial intention to keep them both. In my case there was too much warmth and I wanted more detail and transparency. Eventually I have chosen my amp to stay and got new speakers. FYI I have tried cables in an attempt to salvage things too but in the end figured out a *component* need to be replaced.
Good luck in your cable marathon......
