Hum sound ..is it me or is it you? LOUD hum in system


I sold a classe SSP-30 preamp 2nd week of April. worked fine. I played with it . zero noise at all.
sold it to get a simpler dedicated 2 channel preamp.

nearly two weeks after it was delivered I get an email saying that when the classe 30 is installed there is loud hum...but when its not there is no issue. 

that is all I am told..and "I want to send it back"

im kind of agitated that buyer took his sweet time to get around to checking it out or whatever.  Not sure what to do or what I can do. I told him to send it back so I can see it.

my question is, I read lots of info on grounding loops and funny noises .   because buyer claims he has noise does it leave me any other choice but to take it back?

I used the pre before I sold it for this exact type of reason.  i just didnt take video.   im not to pleased with the extra long delay neither. seems like if you spend that much money on something you check it out right away. it doesnt take a lot to hook up a preamp.

i find it hard to believe a preamp of this caliber would even have ground issues.

I dont know what to do. I feel like I am at this guys mercy no matter what?

Can we all send him small packages of dog turds? I have two dogs and a seemingly endless supply..
that is a tempting thought to send some treats in the mail...


but what does that mean? no one is standing behind the speaker?


all I know is I sold and item complete with pics before and during packing.   forced to refund the buyer and then received a dinged up preamp that is working just like it was supposed to be.

if you are refering to me as the "speaker" well ...I didnt exactly title this thread to draw that many people in.  at the time I didnt think I was going to be forced to refund the crook.  
my feedback from the scammer was reversed BUT so was HIS.

so anyone that sells an item to the guy you have been warned . He will use the system to force a refund. he will claim he was too busy to test it right away but he will not be too busy to move right along with paypal and force the refund.  

I am the 2nd victim but I know there are more.    Not sure why Audiogon removed his negative feedback when I have all the proof in the world to make the case he was a scammer.  In a real court I would have won.

you guys are warned.
