A great, informative review really like you compared different headphones and how well the lau drove those headphones.

Hi, thank you for your review and comparisons with other amps and different cans.  I´m interested in Master 9 and thus I would like to ask you about soundstage comparison between LAu and Master 9. It seems from the review Master 9 holds its own vs Lau very respectfully.

yeh M9 is my favorite Class A amp, if you want a warmer with less dynamic, yet even better mids then nothing beat M9 with that. soundstage wise i  i think LAu got a bigger pne, i used TH900 on both amps, yet it been sometime.
