Looks new and works perfect with good quality parts. I use it with my iPod Video 5.5 Gen via LOD cable and AKG K 712 Pro Headphones. The sound for me is a little better now with this CMOY Headphone Amplifer.
Changed the DIP-8 op-amp with another i got: Deeper punchier bass, more air in the midrange and softer highs, it's more enjoyable to listen to now than without the amp. I like this CMOY Headphone Amp.
Amp arrived in perfect shape. Very good built. Board firmly fixed to tin with adhesive foam. Good high quality volume control with ON/OFF switch, LED inside, on board, nice small aluminum knob finely textured so it wont slip on your fingers. Volume more than adequate, just a fifth of a turn to reach my listening level using in-ear-phones. Well worth the wait of six weeks to South America.
