DBX Expander


I have recently acquired a Teac reel to reel and although it's a great machine, soundwise, it just doesn't measure up to CD or LP's in my system. I have a chance to purchase a DBX sound expander that I'm told greatly enhances the sound of the tape. I have no experience with this box at all. Does anyone have any knowledge of what this does?

If you dial it in properly, I doubt you will want to sell it.
Looking at your system, you may not be into compression*** anymore - but the Impact Restoration on any analog recordings, when not overdone, is addictive. I have my 3BX-DS in the closet, just as a backup in case God Forbid, my 5bx ever has a problem.

***One really valuable use for compression is if you make CD's for listening in your car. By compressing, you can actually hear the quieter sections over road noise, without the louder passage blowing you away. I often wondered why I like the FM radio for car listening better than the built in CD player - that's why.
wOULD YOU BE WILLING TO SELL YOUR UNIT???? i'M CURIOUS TO EXPERIMENT WITH MY NEWLY RENOVATED REEL TO REEL AND A GOOD DBX
I certainly don't want to sell mine, but the 3bx-ds is very easy to find on Ebay. Seems there's at least one a week. And there IS another 5bx on Ebay right now, which is very unusual - they only show up about once or twice a year, and now there have been 2 in 2 weeks. With the economy and market diving, stuff may be coming out of closets...
The current one is missing it's remote control (which is nice, but not at all necessary), so it should go for a bit less than the last one.
DBX'ers : I own a mint DBX 117 that's been in storage for many, many years. Do you feel its worth re-installing in my rig ?
Crem1:

I had a similar single band 118 at one time and did not like it in general for expansion in my system...too much pumping and breathing introduced with only a single band.

I did use it on occasion for compression in order to listen to recordings more effectively late at night at lower volumes.

I do use the 3 band 3bx for expansion in my system currently and would find it hard to live without on many recordings, particularly on vinyl.

Yesterday I played a vinyl copy of "Thick As A Brick" by Jethro Tull that I recently picked up for the first time. It sounded fantastic right off save that the dynamics were noticeably compressed. I switched in the 3BX and things took off without reservation from there. It was sweet indeed!
