Subwoofer for Ayre AX-7e?


Am I wrong or are AX-7e owners required to have subs with speaker-level inputs? I was keen on SVS and discovered that several of their models only offer line-level inputs other than their base SB1000. Looking for sealed cabinet in the $750-1000 neighborhood and feeling a bit thwarted ... suggestions?

Circling back to this thread with a particular question for folks familiar with REL's subs: Does the Arrow wireless system solve any issues with the high level amp to sub connection problem that some have mentioned here?
I have a feeling that the new Vandersteen mono blocks will be too much for me to resist, so I'll probably have to sell my Ayre AX5/20 in addition to selling my Ayre QX5 DAC/Server/Digital pre.....it will be strange not being an Ayre owner if all comes to pass, lol....:)
