hi guys, just came across this site:
http://www.busmanaudio.com/mods.html

he is offering a mod for the dr-680. there he states this:
This modification provides much better detail and natural sound than the st=
ock unit. All of the njm4580 op amps are changed out for high speed, extrem=
ly low noise op amps. The input capacitors are changed out for better value=
s that allow for great bass response with an open sound and smooth high end=
 that has excellent detail. This modification lowers the noise floor in the=
 high gain setting by over -8db.


well, this can not be true. if the dr-680 would have 8db less noise, it wou=
ld be top of the pops and better than the sound devices 7 series.. so, am i=
 overseeing something, or is he just trying to sell his mods?
