Bought an old Alpine 7909 CD player from 1989. It's considered to be the 'HOLY GRAIL' of CD players!
If you know anything about vintage/classic car audio, you know about the Alpine 7909. This unit came out in the late eighties-early 90's.
One of the industry's best sounding decks ever made!
I got an awesome deal on it
Hey, good news ! The power supply was gone on this 7909 unit, so I had the unit repaired..
Sounds amazing ! I Havent heard anything this clean in car audio ever !!
Even the installer was impressed , and hes been doing car audio for 20+ years...
Here's some pics and a video !
