Hi. I'm currently using Logitech Z2300 speakers with my desktop PC. My soundcard is the Asus Xonar Essence STX . I have had the Z2300 for years and like them. However, recently I read several positive reviews for the M-Audio AV 40 monitor speakers. I am wondering if this would be a better choice than my current speakers. Most of my listening is Jazz as well as some vintage rock music.
