My Lyra Parnassus has (or rather, had) a very low output and I can use it with my SP9 which offers similar gain (although a little more is appreciated), so I think you'll be OK.
That said, I think your PH3SE could probably use an upgrade, given the rest of your gear. A used PH7 would likely do wonders to your system!
