Headphone Amp Inventory

O2 with opamp upgrade (gain stage OPA2132PA, driver stage 2x AD823AN) Great combo for portables. A/B X compared with DX100 on board amp. Sounds slightly more transparent, noticably more refined and slightly broader soundstage, slightly darker background, instruments separated much better, more natural vocals though it lost a little vocal depth (still more than acceptable imo) when compared to DX100. Volume is balanced as close as possible in the vocal region. It will be a matter of preference for a fuller sound or more transparent sound. Comparison done using T50RP MK3.

Music Preferences

Anything. Prefers soothing, catchy, fun, or songs that tells stories when the sound comes to you.
Loves good depth for vocals and a soundstage that is laid out in front of you when you close your eyes. Soundstage with vocals above forehead is considered unacceptable, and overall stage should not be too high.

Anything except annoying songs.

Interests (non-headphone)

Games. Anime. Many others...

Gear-Fi (Favorite Non-Audio Gear & Gadgets)

Sony Xperia Z5??
PS Vita
