Oh, I'd agree! I just meant he would 'probably' be 'OK' to do it. "probable" and "OK" were used so as not to present a positive outlook, just that it might be an option. I also said he should call the vendor for the final word on the units true capabilities. Many people run efficient 4 ohm speakers on the better made 8 ohm amps when they are known to be able to handle it via common customer feedback. I can't comment on when it becomes susceptible to audible distortion because it would totally depend on the equipment, setup and use of the volume control. So agreed, not a good idea if you can avoid it. If you can't reasonably avoid it, consult the manufacturer or see if other people have safely run 4 ohm (average) loads with this amp. -- Murph ------------------------------------------------------------------------ Murph's Profile: http://forums.slimdevices.com/member.php?userid=10553 View this thread: http://forums.slimdevices.com/showthread.php?t=39759 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
