I have a Sony XM-260G. It is fully tested down at 2 ohms mono. No anomalies appeared on the scope when driven into 2 ohms. The only problem is that the power light does not work and I have no intentions of replacing the led. Also someone crimped the remote plug I think. Check out the pics. It does not appear to have ever been repaired and appears to be all original parts. Cosmetically, well, check out the pics. Id call it 6/10.
