Killer used integrated for

Bought an Hegel H100 for 650usd. It’s a bit pricier but nothing compare at such price.
You will get depth, great timings and imaging, soundstage, bass, beautiful midrange and Hegel liquid sound signature at 120w@8ohm and 240w@4ohm. Plus a usable DAC. Good luck if you want more.

Not sure how many watts you need, but Vista Audio's Spark is great.

Good luck

+1 on Rega Brio. I just sold one on another marketplace. 

Also, killer is not the word I would use for any of these.

Ps audio sprout 100.
