It's not my strong area, but I am aware that compression algorithms have
improved over the years; IIRC, the Dolby standard was revised with more
DB of compression/expansion. I would check for later devices.
A good check is to see if it is available everywhere or available in
smt. Otherwise you can bet there is better out there.
