What is your favorite budget audio component?


Just wondering for the sake of curiosity and general sharing and education among audiophiles, “What is your favorite budget audio component?” And as a bonus, “Why do you consider it budget and why is it good?” 
Since budget might be relative, I would say audio gear like MBL, Wilson MAXX speakers or anything ultra high end should not be considered.

Bluesound Vault 2....amazing value and performs well beyond its asking price.  
Buying used makes for many a budget audio component.

The original Audio Alchemy 'DAC in a BOX' I bought used on Ebay for $50. I pair it with a Schiit Vahalla headphone amp. Of course I use a M2Tech Hiface USB/SPDIF converter when using computer. 


@mesch I just got rid of mine when I sold my Yamaha disc changer on eBay...

That was definitely a good DAC!

My bargain - my class D monoblocks. ICEpower 500asp modules, quality connectors, nice case.. $600 for the pair.
