Perhaps the PREAMP cannot push TWO sets of outputs to the TWO amps?? Consider the following: the preamps output power is halved going into EACH amp when you have both connected. Therefor the volume control on your preamp with two amps parallel would have to be 'like' TWICE??? the volume setting to give the same apparent power out of the amps to the speakers. (I really am only guessing... but it's an informed guess!) That could be why, also...
Why didn't this biamp strategy work?
I purchased a second Dynaco ST-70 to complement another that I have. I used one to run the highs on my Vandersteen 2ces and one to run the lows. I thought that the doubling of the power would appreciably increase performance. However when I hooked it all up, the soundstage deepened dramatically...instead of Paul Simon singing in my lap, I was now on row 20. Also, the voices were a bit more murky and the bass was not at all improved as I had imagined it would be. I left it this way for awhile hoping to eventually hear the advantages, however finally I just hooked up the one ST-70 and everything was wonderful again...better midrange AND better bass despite halving the power. I was not using a crossover as the amps have the same power curve and my preamp (an Aragon 24k) has dual outs. So there were no added ICs. What happend here? Will vertically biamping help?
