Have a hum through my center channel speaker, the SET amp of which sits directly in front of the pp200 about a foot away. It is not relaTED to the DC offset of the 2000 as adjusting that does nothing to the hum, and running the amp from the wall rather than the 200 also doesn't decrease the hum. Thus the 2000 must be giving off a significant field. Moving the 2000 a couple of feet significantly decreases the hum as does running the 2000 on batteries.
Also have noted a slight increase in ambiance information while running on the batteries but am unsure whether this is due to more information coming through or less hum from the center channel.
The unit does such a great job, far superior to anything else I've used over the years that I've ordered two for a review. Hoprfull that will allow me to run my Crown Macro Reference off one of the units, and the eight SET amps off the other, as with peaks now the pp2000 goes into protective mode with the Crown attached to it as it draws 1500 watts on peaks.
Thank you Romy for the find.
