get yourself adriverack dbx pa2 .it processes everything between your preamp and speakers .yes i know it's digital but for me there is no sound coloration that i can hear.you can bi amp and triamp.it will do everything you need but i mainly use it for crossover frequencies.there is also an app you can download so you can dial everything you need onto your i pad or laptop and adjust all parameters on the fly while listening to your fav lp.you will not look back i promise.just my tuppence worth.
Bi-amping
Does bi-amping only benefit sound quality if your really driving your amp hard? I have a Mark Levinson 23.5 which is pushing my B&W 801 series 3. This amp is a beast and I never push it anywhere its max. I have an opportunity to purchase another 23.5 but don’t want to buy it just to buy it. If i’m not going to benefit in sonic performance, I wouldn’t want to do it. Any thoughts?
