Looking for a warm sounding amp or integrated with a torodial transformer

Looking for recommendations for a warm sounding integrated amplifier or power amplifier tube or solid state with a torodial transformer power supply. I have multiple chemical sensitivities and the materials used  in the rectangular transformers affect me, I'm fine with toroidal transformers. I've been looking at BAT, Modwright, and Pass Labs. Any other ideas? I have a Rogue audio sphinx but would like a bit more warmth.

Thanks in advance!
