The Sony ES1000 digital pre I once owned, (bought new too)is a $100 pre connected through a pile of crummy gizmo laden digital filters. I was overcome by it and sold my Hafler DH110 for it, It was the very worst mistake I ever made in my audiophile career. I went from total bliss(Dh110), to not listening at all (Sony)... and it took a year to realize why!)
Don't do it.
Don't do it.
