I agree,to a good extent,with Rushton.I had a battery powered ROWLAND 8t amp that although is a diff. component,also similarly,had unacceptable dynamics,compared to the updated switchmode power supply that I had Jeff install,replacing the battery.I've never looked back,and,also,have Avalon speakers(the Fabulous,yet forgotten)Ascent mk-2.With the resolution of your system you should go for the best and look at it as a last purchase.
