I recently bought the denon 3808 based on a number of reviews on this forum and purchased from 6ave.com based on the deal mentioned several times here. When it came in the mail I was elated to find that I received the 4308 by mistake. After a week of use I get a call from the shipping manager saying they made a mistake. He wanted it back. I told him it was not my problem for their quality control problem. Jeff Fish (Fitch) got very crappy with me and said he would send the authorities out if I did not comply on a charge of grand theft. - For their screw-up. After contacting the authorities and a lawyer I found that we was full of crap and just wanted to strong arm me. After confronting him with this he said I would have to pay the difference. I told him it was not my problem but I would work with him. He offered to overnight the 3808 and give me another 100 off for the inconvenience. The next day I realized that I did not have the box. I called back and informed him I did not have the box. He sounded chastized me for not keeping the box. I told him I set it up, it worked, why keep the box. This is where 6ave really starts to get shady. He said "Great, now I am going to lose money on this now." The only way to take that is he was going to sell this receiver I had been using for over a week as still new. Now I didn't have the box he had to sell it as used. He said he was going to have to charge me for the difference now. I said "No, you do not have authorization to charge me. I will return it once you send me my receiverr and a box." He tried to claim they have no boxes and hung up in a huff saying he had to try and find a box. That was 3 days ago still no box or call saying he found a box. I filed a complaint against this company with the Bureau of Consumer Protection of the Federal Trade Commission, BBB, and will be contacting Denon to let them know the kind of customer intimidation and deception practices with new vs used products this company uses. Also of note, if you search for this company on BBB.com there are several entries for this company. Make sure you total up the numbers between all of them and you will see numerous problems with this "reputable" company.
