No simple and this is the reason you ask for active gain line stage when your power amp already 300 watt. I'm not gonna say your speakers are bad, but they are power suckers for a reason.Rediculous. Now your telling me I need to pick speakers I don't like just so I can use a passive preamp? Which can't be passive anyway because of the need for buffers to work with the Herron?
There are compromises in any system, but I'm not going to compromise on my speakers any more than my budget forces me to. Don't hijack my thread and go preach your cult mantra someplace else.
