High level modulation is not necessary to reproduce natural asymmetry which shows up with good frequency response. Unbalanced balanced modulators do an excellent job of this. That's what many older ricers use. Plate modulators need low mod transformer ratios (when using a common supply) just to reproduce normal asymmetry. Many male voices can modulate easily to 140% positive without exceeding 99% negative if the bandwidth is correct.

I would not consider a TS-870 an excellent sounding AM rig. They sound OK but lack highs. If that's all I had then fine.
