Cable/interconnect for Sonus and Musical Fidelity?

Hi Folks,
My system consists of
1)Sonus Grand Piano Home, Solo, Wall.
2) Musical Fidelity A308 integrated
3) MF DAC
Recently ugraded to these components and I'm looking for speaker cables and interconnects. Trying to stick to the same brand for both. Every audio shop I've talked to have given my a different opinion because they're trying to sell me the stuff. Any input from anyone with a similar system would be appreciated. Thanks.
