Hi everyone
Sorry for not getting back to this thread earlier. I have some updates regarding the Millenium Carbon Fiber CD-Mat, my Oppo BDP-83, and the CD-Mat getting dislodged.
When I used the Oppo BDP-83 to play CDs and SACDs with the Millenium CD-Mat the CD-Mat NEVER got dislodged or mis-alligned. It only got mis-alligned when I was watching Blu-Ray movies. The last movie that the dislodging occured in was Rambo (2008 movie). I was using the ending action sequences to test out if I calibrated my HT speakers correctly. Nothing like bullets and loud explosions to test your HT rig. ;) This was when the dislodging occured as mentioned above.
For a while I did not use the CD Mat with the BDP-83. I then recieved an e-mail from a fellow A-goner Klassikalfan. He detailed a very simple yet in-expensive fix to my dilemma. Below is what he told me.
"I have a new Oppo BDP-83 Special Edition player - and use both the "original" Millennium Mat and a slightly better one made and given to me by a friend. Same carbon fiber, but .5mm thick instead of the MM's .3mm. Both are equally "revealing" in sonic quality - BUT - your concern about a sliding mat does have a simple answer, used by several of my mat-using friends.
Just get some Scotch Poster Tape - it is "removable" tape that's double-sided. Cut out three squares about 1/4-inch or so and press them into the "rough" side of the mat - the side touching the playing CD. Rub the tape in, then gently remove the paper on top. Now, whenever you put the mat on a disc it will "stick," but just enough to prevent sliding. Gently pull the mat off after playing. If the tape sticks to the CD you haven't rubbed it in enough on the Mat. After a month, the tape on my mats is still sticky enough to work just fine. A cheap and simple solution that really works.
When you get your Poster tape -be sure it is the REMOVABLE kind - there are two kinds, and one of them is permanent. The one I use says "removable" right on the side of the Scotch dispenser. Use three very small "dots" - each about a quarter inch across - and rub them into the rough side of the mat thoroughly, then peel off the paper."
It tested my patience following what Klassikalfan's tip but it was worth it. I've watched many movies since and haven't had an issue.
Now as for SQ improvements that were provided by the CD-Mat it was a toss-up to me. Some discs there was an audible improvement I heard in clarity others not so much. Either way I'm keeping it and may get another mat for my secondary system.
Anyway I owe a very big THANK YOU to Larry aka Klassikalfan for taking the time out to contact me and answer my questions. People like him keep me coming back here.
