The input jack issue was only a problem for a limited number of units in the first run. I don't know why people keep making a big deal about it, because the units since that run have been rock solid. I have 50+ stealth shows on my unit now with no issue.
My R-09 wasn't from the first run, and I too had 50+ shows without issue... Then out of no where the line-in jack disconnected from the PCB.
IMO their fix of adding a drop or two of glue was/is hardly an adequate fix. It is simply a poor design.
If you can post the serial number, it would be possible to identify its age.
Ser # BU91186
The jacks in this unit had the white silicone / glue between them and the PCB.
This glue was Edirol's fix for the problem on all the newer units. While better it still is weak. The input jacks should have been fastened by posts going through the board, like the headphone jack is.
Edit to add: Don't get me wrong, I love the R09, it just sucks to pay that kind of cash for something and have break because of a poor design that probably saved them a few cents per unit in manufacturing.
I really hope the R09HR has the problem fixed.
