J-FET technology Package Outline: DIP8 Applications: Hi-end Audio & professional audio equipments Review: Best OpAmp for the price and performance 135db 0.00004% THD which means audiophile performance on a budget. - I'm putting this chip into a Xonar DSX 192khz/24bit sound card which currently has THD of 0.0017% with the MUSE8920 it will go down to 0.00004% which is substantially cleaner sounding and will allow the fidelity of the sound to come through. Now I just need to build a decent set of speakers... or replace speakers on a old set of speakers with higher quality ones..
