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.

My latest purchase, Audeze LCD-2 headphones are really quite fantastic.  I have never owned a really good pair of headphones before.  Now that I have a baby asleep, my hifi sessions are limited :-(
The headphones are opening up a new mode to listen to music!
The Chord Mojo portable headphone amp/dac is another budget favorite.  Though these may be budget cost items to an audiophile, one must note that $1,550 for headphones and a headphone amp is rather exorbitant. 
@inna +1!!! I am Senn guy otherwise this is the Way! R2R or Nak cassette deck? With tapes recorded off LPs, nothing beats that to my ears! But the price of admission is kinda $$$!! I mean for the newbies with no access to dad's stereos
Yamaha A-S801 Integrated Amp ($899).   Good sound, flexible, built-in 32bit DAC.

Sonos Connect ($349) with Deezer Elite subscription ($20/mo).  Easy 16-bit FLAC streaming.  35mil+ songs.

One of the things I really like about Audiogon forums is you learn about gear you'd never heard of or considered.    Based on this thread, I now might try the Omega Super 3i monitors in my second system.  Thanks Audiogon!
