Jfrech,
If you're still looking, you might check out the review of the Shelter 90X at:

It seems like it might be what you're after. The reviewer compared it favorably to both the RSP and the XV-1s.
It's got enough output to address the issue Raul just mentioned. In fact I think Raul's heard the 90x and could give you another firsthand perspective.
