In my opinion, this is one of the best small headphone amplifiers

my littledot mk ii just arrived in the mail, I know the tubes require 48 to 72 hours of burn in with music, but just right off the bat after a minute of listening to this awesome amplifier, it sounds so good

Dot mk 2: excellent headphone amplifier without any disadvantages; suggestions for alternative power tubes would be appreciated.

straight that dayI absolutely LOVE this amplifier, there is nothing else that beats the quality to price ratio that Littledot and the Shenzhen Audio store has provided
