Can we increase dynamics?

Jjrenman, Just 16/44.1 CD files.
John, I found so far that compression is far more complicated than just squeezed dynamics while your experience proves it to be difficult to properly set. I think I might play with software but will definitely avoid investing in hardware.

Thanks to everybody for posting.

Thanks Brf, I'm reading about them. I wonder if there is software for that. It would be cheaper without expense of second interconnect. Even if 16 bit doesn't have enough range I would purchase some music in 24 bit.

Al, thank you. I will check version for the Mac. I could always install dual boot. I'm a little worrying about dynamic range limitation of CDs (96dB) unless filtering (that increases resolution) is involved. I will investigate hardware digital domain Berringer that Elizabeth mentioned (thank you), but Sound Forge is a program I can have fun with.
Markpao, thank you for the warning. I will be very careful especially because Hyperion Sound, manufacturer of my speakers, pretty much bankrupted - no replacement drivers.

Ngjockey, Looks like it might be more complicated than I anticipated. Perhaps it is not worth to invest a lot of money in hardware but rather play with programs (keeping original file intact, as Al suggested).

Plato, I don't listen very loud but it is important observation. I will be careful with expanded files. I will likely only experiment but can see some other applications for "Sound Forge", like removing noise from few old recordings. I learned something new today.

Onhwy61, Ngjockey also mentioned that compression is pretty complex. It explains why expanders are not that popular. TV concerts are the worst - so overcompressed that it becomes a joke. Perhaps it is intended for TV set with the smallest speaker. Even less than perfect decompression would be good but it would have to be SPidif-in SPdif-out (I use Toslink to DAC).
