HEY GANG...

Someone locally has a 7903 for sale. what is the difference between the legendary 7909 + 7903 ?

seller said that :
"Not sure if it plays cdr's, it is basically the same as 7909 you are looking for butwith the 7909 has Burr-Brown DAC and "audiophile" grade components (whatever that means), no changer controls and no power amp built in, pre outs only."

here's some pics

Yeah...as you found, the only one worth thinking about is the 7909. Forget all the rest.

The original 7909 has the "pull out" feature. Basically, you can slide out the head unit from your dash. While so many people jump up and down yelling, "that's cool," The consumers in Japan will not accept that. The pull out feature results in each connection, each contact meets a barrier since the 7909 basically "plugs into" it's cage. In other words, the signal is sent, met by the cage terminals but still needs to send that signal to your amplifier...it's not a constant flow. 7909J on the other hand does not have the pull out feature and, each connection, each contact has a direct path to your amplifier. Believe me, that pull out feature was a major failure in the 7909. 2.) One of the pictures show a small black box marked, "Alpine." That is actually a small external DC/DC convertor....the results is a cleaner power supply, cleaner signal and a more solid image. 7909 does not have that. 3.) 7909J has a "Black Out" button. Press it and all lights on the head unit are turned off. This allows a cleaner signal as a result of less interference and full voltage being needing to feed only the laser and spinning mechanism. I need to be honest here, I am not 100% sure but my understand is that 7909 does not have that feature...If any one can share some information on this, I'd much appreciate it. While we're at that, this 7909J comes with a copper case. Does the original 7909 has a copper case as well? 4.) Vocals are cleaner. There's more detail with out the brightness that 7909 has. Fully tested in my car for 5 full days and functions so sweetly! Comes with only what is pictured...sorry, no box or manual. This is abviously used but functions 100% as new. The face still looks very presently and shows no marks....exceptionally clean face/diplay...Happy bidding and good luck to the lucky winner! This is by far the most pretigious and limited unit that Alpine has ever made in history, period!

I call BS on the poo-poo of the pull out connection. Every deck has a plug in harness, consider the pullout connection on the 7909 the same as a harness. Yes the RCAs are on the pull out connection and on a standard deck they are hardwired to the board. IMO not a big deal. Copper chassis' are a marketing gimmick as well. Zero functional purpose. Same as the blackout 'feature' - that actually made me laugh out loud.

Personally I would not own either. I had a 7909 back in the day. I was happy to get rid of it
