Yeah, if the album is good, you're going to notice improvements in quality.

It probably depends on what you're listening on (high quality headphones may make the differences more noticeable) and how the audio track was mastered in the first place (if the mastering studio just boosted the volume to make the sound LOUD or if there's actual audio range and quality in the track)

If you want to experiment with lossless audio, I'd suggest  The Future Sound of London - Lifeforms (1994) or Mike Oldfield - The Songs Of Distant Earth (1996) or Enya - A day without Rain (2000)  . You'll definitely hear the differences if you listen to these and then listen to what's on youtube or a 320kbps album you download from somewhere.

I'll definitely try them when I get home as the internet is bad atm. I'm using DT770 Pros, it was sort of an impulsive purchase but I now understand all the hype around the Audio community. 

Are you downloading uncompressed or FLAC?
