Yes you can do it for $50 New (not used), which is fine for the level of your system.... Speakers: Wireworld Luna III $50 for 10Ft. (3Meter) w/spades; Audioquest Type 2+ also $50 for 10Ft & Spades; MIT Terminator 5 $45 for 10Ft with gold posts (little more for spades).... You can go shorter to 6 or 8 feet on most of these and save +/- $10; get a second pair to bi-wire.
Interconnects: Straightwire Chorus $35 (0.6 meter); Straightwire Harmony, $25 for 1 Meter, $18 for 0.6 Meter; MIT Terminator 4, $36 for 1 Meter; MIT Terminator 5, $24 for 1 Meter....Happy Listening. In that range the SW Chorus would be my first choice.
