SET amp recommendation

Recently made the switch from Cary 805 AE to Atma Sphere OTL pre-amp and amp. The OTL dynamics and sound is where I live now, but still looking back over my shoulder at SET. I still have a Cary SLP 05 preamp with no one to play with. Can someone give me a recommendation for a good used SET (any configuration) amp for $1,500 or less. See a lot out there, but could use some guidance.
