Well, this thread had to get me going and thinking about new speakers for my computer. I've been to many local guitar shops these last few days listening to brands like M-Audio and Alesis. Some like, M-Audio were too bright for my tastes and I felt I would get listening fatigue after a short while which isn't the purpose. The only Alesis I heard were the low priced ones that really didn't let me know how the better models might sound. Then, I found many complaints about the design of the model I was considering, the M1 Active 620, that led to problems with internal circuitry giving out due to heat.
So, now I felt stuck, wanting new powered and musical speakers for my computer. Finally, I ended up purchasing online speakers I haven't even heard, Audioengine A5's. I did this based on what seemed to be universal acclaim for the product. They're relatively inexpensive compared to the others and there is a thirty day return policy.
I'll let you know if I like them. I want darker sounding speakers to avoid fatigue and, to me, sound less digitalized.
