Audio-gd CD7-FV - Reviews
Pros: Fantastic sound quality, sturdy remote control, built like a tank and user-replacable lasers
Cons: Weak plastic tray, some audible mechanical noise coming from the drive
Perhaps the most over engineered CD transport ever built. Fantastic synergy with the REF7. Its largest problem is the weak plastic CD tray that could easily be accidentally broken with too much force. Otherwise it´s built like a tank. Looks suprisingly good too! 
I originally wrote in 2011 that it´s hard to review a CD transport these days: today in 2016 I would say they are obsolete. But if you are looking for the best way (judged by sound quality) to feed a REF7, this is it.
