Akai 747 w/DBX question

Hopefully there are still some reel to reel folks out there. So I currently have the 747 w/out DBX, and I have an opportunity to pick up the DBX version from a local person who owns a rather hi end audio store here in town. My question is: Is the Dynamic range extension worth the extra coin over the non DBX version? I don't record music from CD's to tape, and the added DBX if it works well should do wonders for recording from vinyl. I have owned reel to reels all my life but never this piece. Just curious if its worth the effort, and if you think it will it be an improvement.  

Well well well what do ya know. That’s good! Ok I feel better now. I will perform the operation and see if it makes a difference. I am not really having s problem per se but if you guys recommend it needs to be done, and I have the right equipment to do it why not. 
Hey thanks for the info. I really love my reel to reel and I have had one since the 70s and I want to keep it in top working condition. I have it serviced once every two years so I Know the heads have not been de-maged at least since then, if even. 
Ok guys. I’m about to de-mag my tape transport and heads. Hope I don’t blow anything up.
