EX vs RG

Hello good people, Always looking for Pioneer audio that I have never seen or heard of.... While researching my Pioneer goodies. I came across the PIONEER EX 9000 DYNAMIC EXPANDER. That leads me to ask what does it do and what is the difference between it and the PIONEER RG# DYNAMIC PROCESSOR. Peace JP

I checked the Pioneer database and see the EX-9000 was manufactured between 1985-1991. Looks to be the last generation of dynamic expanders Pioneer produced, surround sound becoming more prevelant during that time. I haven't used or seen that particular model, but I do own the RG-2, RG-9 and RG-60 dynamic range expanders, so I assume the EX-9000 accomplishes the same effect as the others. Hope this was helpful and accurate.
 
I am not sure but RG range expanders were originally manufactured by RG, they were bought by Pioneer, I would have to wonder if they didn't keep the RG part of the name and then later decide to leave it off.

Do a search for RG range expanders, they looked completely different than the later Pioneer RG range expanders, RG also made a fairly nice preamp. I believe that RG was in Skokie IL.

I have the rg1 rg2 and the ex9000. I prefer the ex9000 by far. Seems to be the quietest one of the bunch. Also has more features than the other 2 as well. The 3 expansion levels are a very usefull feature. It's not a very big unit but it's quite heavy for it's small size. I'd grab another in a heartbeat should I get lucky enough to find another one.

Where I hear the difference is in how it definitely expands the sound of vinyl. For me there seems to be more presence and/or significant difference in channel separation. You can switch it "on" and "off" per your taste. I have read posts on EQ's (which I also like to use to tailor the sound) and there are those among us who like them and those who won't use them. For me, there are music sources, be it vinyl, tape, CD, what have you, that can benefit from the sound enhancements that dynamic expanders and equalizers have to offer. However, overdoing it can make the sound sound unnatural and/or artificial.
I like to hear the "highs". I want them crisp sounding and not flat or muddy sounding. Just my 2 cents.
