Pre/Pro with

I've been thinking about using a pre/pro as a pre for a 2.2 channel audio only system. I'd love Audyssey XT and balanced connections. On this basis, the Integra 9.9 looked good, but there's one issue:

Some of my speakers cross over from the mains at a high enough frequency that maintaining L/R signal integrity to the "subs" is important. My Verity Parsifals cross at a recommended 150hz. Any pre/pros out there that offer "non summed" L + R sub outs?

Thanx in advance,

Marty
