Two things. First, make sure it is recapped, or you will be playing Russian roulette with your speakers. Don't bother changing the power cord, unless it is damaged. Second, beware of older speakers. Speakers do age, and not just the capacitors in the crossover network. Cone surrounds in particular will often have dried out.
Best speakers for Pioneer SX-1250 receiver
SOME QUESTIONS PLEASE REGARDING A VINTAGE PIONEER SX-1250 RECEIVER (160 WATTS PER CHANNEL INTO 8 OHMS/200 WATTS PER CHANNEL INTO 4 OHMS). WHAT ABOUT THIEL 2.5 OR PROAC 2.3 OR SOME OTHER USED SPEAKERS IN SAME PRICE RANGE AS THIEL/PROAC. DUE TO THE AGE OF THIS UNIT, WOULD IT BE ADVISABLE TO UPGRADE THE POWER CORD TO A IEC CONNECTION THAT WOULD ALLOW FOR A VARITY OF POWER CORDS. ANY OTHER SUGGESTIONS FOR THIS UNIT THAT IS IN GREAT CONDITION? THANKS.
