How does it sound?

 

[digi01]

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.
