Reply to whats your setup using the s4?

God forbid something to your s4s. But I was wondering what would be a good back up to the s4? I do have tech 1200s but like those suggested on here those aren't backups. When you gig with the s4 what other hardware compliments it? Maybe two x1s?

I love the s4. I even thought about selling my 1200s to get numark ttx usb turntables for home use. I believe I would regret that.
