I've just inhereted a great pair of ADS 1590/2 tower speakers that I want to put to use as the left/rights in my home theater system. They are monsters with dual 10" woofers. Problem is, they are very hungry speakers and I'm concerned about trying to drive them with my Onkyo TX-DS595 at only 75 watts RMS per channel. I have a great Yamaha M65 power amp which puts out 170 watts RMS per channel that I'd like to use to drive these speaker. So, I'm asking if there is a device available to convert the speaker level outputs from the Onkyo to the RCA level inputs that the Yamaha power amp requires? And, is this a practical approach? The Yamaha/ADS combo really kicks butt when playing stereo and I'd like to put that sound to use in the home theater. Any thoughts?
