I am currently running a Mesa 50/50 with my Quad preamp but still to loud. If i run the the 50/50 in 1/2 mode,it does'nt sound as good as the full power mode. To get the Quad to sound great, i have to open up the 50/50 about half way up. Now its blistering loud. Do you guys think the 20/20 would sound better at lower volumes ? Would the 20/20 make a good match with the Quad preamp ? Or should i look at some other type of power amp all together ? Any help and ideas would be great,thanks.
