OTL
Output Transformerless

Audiophile speak for "I spent big money on ancient tecnology because I'm better than you"

This is an amplifier design used in vaccuum tube headphone amplifiers where the output transformer is omitted, making them cheaper to produce, while milking audiophiles for every last cent. In other words, pure profit!
I love the sound of vinyl through an OTL amp and Grados

OTL
OTL is a stick figure of a person on all fours. O= head, T = arms on the ground, and L = legs. The lowercase form is orz.

This emoticon can be used interchangeably with *worship* which simply means that you are grateful to whomever you present the emoticon to. You use it on someone you really look up to, or someone who just gave you valuable information, or someone you just want to be like.

In some Asian cultures, the emoticon symbolizes crawling, and can indicate frustration, desperation, or even despair.
