Hey, slow down, you are getting ahead of me now ... :-D One of my (two) power amplifiers is starting to show it's age. spewing out little bursts of noise at random intervals. So they therefore both are in in for a replacement. The target is a set of JBL Roadversion from early 80:s. They have a steady drop of 3dB/octave north and south of 1000Hz, easily corected by setting bass and treble on ones simple keyboard mixer at two o clock. They have been beaten and kicked by amateurs when hired out as well as endured all of my own mistakes, but are still perfectly functional ... In other words, these are the WW2 Willis Jeep of loudspeakers, not going anywhere. Anyways ... Finding a replacement for the 250 Watt ACM1 with no fan (silent!) that I am currently using proved to be a challenge though. People are not building that kind of gear these days anymore, at least not within my monetary budget. Findig a silent poweramplifier in the 75 - 125W range is a lot easier, so ... Why not feed the two 12 inch's in each cabinet from each of their own poweramp, using each a souurce of their own? This would be the equivalence of - no, actually just like - using two DAC's in paralel that you proposed above. > > BR, > > - Jussi > _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
