Size wise would prefer no bigger than Amazon echo spot ideally.
Right....well that is small.
I think something bigger (but still 'desktop' sized) might do more justice to your turntable.
If it really has to be small, then maybe a Bluetooth speaker
with an analogue line input.
Probably discontinued now, (no doubt it is, as this video is 10 years old) but something similar to the Kitsound Hive that I was given.
I didn't hold out much hope for the sound, but it was surprisingly good.
Having said that, I'd still go for a pair of something bigger (more audibly proper) if I were you.
