Received the AM Tubadour V today. I believe the first off the line. I previously was happy owner of Tubadour III and decided to upgrade. I hoped for an improvement over an already great dac. With only an hour of use, wow, a big difference already! I'm not good at descriptions but will do my best. Improved soundstage. Instruments have a distinct position on the stage. Excellent clarity with all instruments and voices. Dynamics are fantastic also, as guitars and pianos seem to come right out at you. Very enjoyable and I am playing cds as if for the first time. Hearing music I didn't hear before. Much more is improved but not sure how to put into words. Audio Mirror Tubadour V is a winner and I just wanted to share my experience.
