It's popping when there is no material playing. When the HDMI input is selected I can hear a hiss through the speakers - hiss with a bit of popping, like it's picking up the phono amp on my unit somehow. I would be kicked out of my apartment long before I turned the volume up enough to cause clipping on my PSB 7 speaker set up ... My original conclusion, and that of the " techs " at Marantz, is that there might be a problem with the analog amp of my Refurb unit somehow interfering with the DSP's of the unit. I'll find out definitively tomorrow when I get the Denon x 4000 up and running. I doubt I'll encounter the same problem somehow - I just thought as an afterthought, there might be some benefit to getting one of these power conditioning devices over the surge protectors I have installed.Power conditioners have there place but they do not fix what you describe. Distortion is caused by either over driving the speakers or the amps. The "popping sound you heard is called clipping and again is the result of pushing the amps to hard (not good for the speakers)
I do recommend something like this Ethereal power manager the ones you saw on ebay are not worth it.
Thanks for the tip - if I have the same problem with the new Denon then obviously it's an interference problem - and I'll order one of the above ... ( an extra 40 dollars shipping to Toronto unfortunately, but oh well ) .. I don't have a rack mount system - just a typical home theater setup.. do these have to be rack mounted or could I just throw it on top of one of my subwoofers or something?Oh ok I misunderstood you in your first post. Its possible that the apartment blocks power is dirty and certainly not unheard of in that situation.
Yes, its a great deal for the Ethereal. I have two of them and I like the fact they have readouts for voltage and amps. They also have a built in trigger for some of the plugins.
No, none of my friends have turned into AV junkie's like I have / besides my one buddy from the gym who just spent 200 dollars for one of the above ( the guy who suggested it might be dirty power in the first place ) .. But I will definitely keep this in my purview going forward - again if I run into the same problems I'll definitely order one. Might just take me a couple of weeks ( all in the new AVR will have run me 1220 dollars, so I'm a little hurin' ATM ).Rack mounting is optional. They can be place in a normal AV rack or like you said on something else.
Do you have a friend that might also want one? that way you get two and share the shipping cost? Im over in Edmonton so I understand the shipping issues.
Ok, thanks for the info. The above is a little rich for my blood right now - but will definitely consider the cheaper of the two!+1 for the Ethereal - a great value. You don't need a rack mount, they have feet on the bottom. If you need more outlets, they have a larger version (which does not have the rack mount ears):

Pretty much the same design as the Belkin PF60 (minus the switchable timed outlets).
Yes! I read about this as well - apparently with the 007 series. Mine just happens to be a refurb 6007 - and I actually pm'ed someone who I read was having problems similar to mine. This was his post:I recall that some Marantz recievers had a popping sound problem but I don't know which model. I think if you google" marantz makes a popping sound" you might find some info.
There are posts on AVS forums about the floor noise interference. In fact this is the reply I got from the PM I sent to one of the OP's:I did a little more digging and the Marantz recievers that had the problem would make a loud pop and then go into protect mode. I don't think that is what your problem is. I googled "Marantz pop of death" and got the info.
I've already got everything hooked up through surge protectors - just in caseIta always a good idea to have a good surge protector on your system in any situation, I would still look at getting something even one of these Triplite isobars is a great option.
