Perhaps best state the exact model of those but for PC audio/nearfield many an old/vintage speaker have found new life mated with cheap but hifi sounding T-amps? Look at stuff like the Lepai TA2020 and TK2050 based amp like Dayton DTA100-A, Topping TP-22, etc
well. thanx for reply and few days back i googled especially about lepai t2020, my main priority is to get low freq bass, is it sufficient to power these oldies?? i gave a look at the national market, Bangalore (well known for china products), many options were there real cheap starting from 8$, but can u tell which type of amp(class, considering it's a china product), omh required, etc,,..
