With good ears you'll hear a difference (if it's a noticeable step up in quality). When there's really a difference then you don't have to be an experienced musician to hear it.
What i've noticed the most personally, is the stereo image. Like when you close your eyes and listen to the music... how much do you feel like you have a stage in front of you / around you, and how good can you tell apart individual instruments, how good can you "place" them on the stage, how much little details you notice in the sound, etc.
I have noticed this with good speakers (monitors), headphones, preamps, cartridges, etc. For me personally, the stereo image and "definition" (dynamics maybe) are always what i notice with more expensive stuff (no rule without exception tho).
There's more to it if you get technical i'm sure, but i always noticed the above the most.
The real benefit of using quality equipment with an accurate sound reproduction and good stereo image, dynamics, blabla... is simply that it's nicer to your ears if you really start to listen and compare. In general if you love something that sounds good, you'll always appreciate a better sounding product... BUT...
In the end it doesn't really matter how good your gear is (i believe the cheapest entry stuff is usually garbage and a rip-off, but you don't have to spend thousands to get good quality either). I have never in my life listened to music that i liked, made a beat that i knew was gonna be good... and thought "hey, this music is really well mixed!", or "wow, my equipment sounds really good!". When music is good, it's almost always because it's just that... good music, no matter if it was recorded in a multi million dollar studio with a neve console, or with an old tape deck in someones living room.
I guess i'm just trying to say you shouldn't focus to much on the gear (the stuff you are planning to get all sounds more than fine regarding quality). Just start out with what is really needed and make music. If later down the road you feel like the quality of your musical "chain" isn't good enough, you can still upgrade individual things like the cartridge, etc.
Too many people (me included sometimes) get hung up in the thought that better gear will let them make better music. In the end it will only make the music sound better, and if it's shit music, it'll just polish a turd.
