Recommend a desktop nearfield speaker for me

I'm a bit confused as to whether "bookshelf speakers" are designed to be listened to from a distance, or if they are suitable on a computer desk where the distance to the ear is only ~2 feet. Or, if they are equally good in both situations (which seems to be tough).

I understand that nearfield speakers are optimized for small distances, but they are mostly active speakers, and I need a passive speaker.

Could someone recommend a passive nearfield speaker or bookshelf speaker that works well at small distances, for use on a computer desk?

My tube amp (LTA UL+) puts out 20 Wpc into 8 ohms.

I'm considering:

1. DeVore micr/O
2. BBC LS3/5A speakers such as the Harbeth P3SR
3. Focal Aria 1, maybe Sopra 1 if I stretch my budget. However the recommended amp power is 25W - 150W whereas my amp is 20W, so might not be ideal.
4. Omega Super Alnico High Output

Which (or others) might be best suited for my amp and 2-feet distance use-case? Also, the smaller the better...
