Koss DVP2161 Compact DVD with MP3/CD Player
Power supply improved?
I bought one of these with some trepidation after reading the reviews posted here--in particular, the concerns about overheating due to a poorly regulated power supply.  <br /> <br />The unit I got (not from Amazon) was factory-refurbished by Koss. (it wasn't much cheaper than a new one--so I'd recommend buying new.) To my surprise, it came with a switchmode inline power supply, rather than the linear \\"wall-wart\\" supply described by some owners. My trusty Fluke DMM showed the supply's open-circuit output to be 12.21 volts--very good regulation!--and the player was not noticeably warm even after running for a couple of hours. <br /> <br />Now, I can't guarantee you're going to receive the same AC adapter I did. But it looks to me as if Koss recognized that they had a problem with the old linear supply and replaced it with something a lot better regulated, thus eliminating (as far as I can tell) the overheating problem.  <br /> <br />With that trouble spot gone, this is a sweet little player for the price...and an exceptionally versatile one, as others have mentioned. <br /> <br />Andy Baird
