One other thought.

When I do smaller nursing home/assisted living gigs, I'm hoping to use one amp. I tried one Bose Compact, running two outs on my Tyros into one in on the Bose. It was OK at best.

My hope was that I could use my SSV.3 as a single amp for these smaller gigs. I haven't done that yet, but comparing(using the Tyros) one single Bose to a single SSV.3(my larger den) the SSV.3 wins every time....again to my ears and in my den.

Time will tell.
