My unit was an integrated amp so it was impossible to decide how much of the improvement was due to the separation of the power amp form the power supply and how much the preamp. But the better cable was definitely a large improvement.

I ordered a new umbilical cable for my Musical Fidelity M3, another 2 box unit, from Sweetcome in Hong Kong and it made a considerable improvement in sound. Bear in mind that all parts on a commercial product, even good quality expensive ones, are economic compromises between the best and what is economically feasible. Usually $100 in added manufacturing costs can add $1000 to selling price. If I were able to get a custom cable made up I would. Somebody like Signal Cable could do it reasonably if it uses standard connectors, using Oyaide power cable would be better. If it fits your connecters you could buy some and have a local technician make it up. By using a longer length I was able to separate them more, which also helped. Both increased separation and better quality cable are helpful IMHO.
