Nice work. I like the glossy black enclosure, too.

Do I recognize you from head-fi?

The sound is more magnificent ,what I like inside these experiment OPs most is OPA134.
By contrast,OPA627 has lacked some artistic sense,it technological flavor is denser , Not able to listening for a long time
The LM6171 sound is more sturdy,good bass,very suitable for the playback of the fashionable music.
