I am having 12 year old sony Hi-Fi V-60. It's speakers are damaged also the CDs are not playing now. But is amplifier section is good. I am thinking of buying a pair of bookshelfs for music. What is the expert advice on this. The old system is arted 2500 W PMPO. May be like 80 W in rms. Impedance is written as 6 ohms.
