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.
