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..
Review: Four Stars - Pro tip: slide some floss under the existing chip, then pull it out. For those lacking a chip extractor.
