Very small Integrated and speakers used


I was looking for a pair of affordable powered speakers for my dorm room, and i was thinking that probably i'll be better served with any integrated and passive speakers produced in the last decades.
Now the problem is that i don't have a lot of space on my desk, so i was wondering what are the smallest good performing integrated amps and speakers that can be bought easily in the used market.
thanks in advance

My budget is around €300. I'll probably hunt some bargain on ebay.
I wouldn't minde tube/hybrid but it probably is not as reliable and safe and small.

Powered I was looking at: Yamaha HS50, Adam a3x or audioengine

As for amps theres a few:
NAD c326bee
Yamaha S500
Creek Evolution
Audiolab 8000 series
Rega brio 3, mira
Pro-Ject Stereo Box S (?)

What is out there from Chinese brands? I came across the Maverick Audio A1 but it seems more headphone oriented

As for passive speakers i don't know. Back home i have an old Kenwood KA-52 with Monitor Audio Silver S1 speakers. I was also wondering if i should bring them to my dorm but sometimes i go there.

btw i already have an external audio interface/dac
Audioengine 2 or 5. I use the 2 on my desktop. It's good for streaming services such as MOG. I had worse when I was a student.
you can get an emotiva xda dac-with volume control for $199 + (per yyz) some powered audioengine 2s for around $200 or less--should be a nice set up within your budget.
Matttcone I just received the mINT on Tuesday. I am using it with my new Minny Magneplanars and the sound is wonderful. I also have a Schiit Bifrost DAC that I can use with the mINT as well, not sure what I like better.
REGA Brio amp, Rega R1 speakers and choice of source (e.g either Rega DAC or PLANET cdp )
