can anyone tell me what speakers match up nice to a musical fidelity a3 amp
and a3 cd.

Lots. Listen to some, preferably in the room you'll be using.

what interconnect will give more bass with this setup.i would like
floorstanding speakers. any reccomendations please?

Anything reasonably thick, with clean connectors.
You'll maybe have to pay big money for good speakers. Don't be conned
by the interconnect myth.
