Yes, I had the same (bad) experience. First, I put the new firmware on my A3000, and WOW: it became very fast! The navigation was fluent, i have never seen my A3000 like that. Then, with this great new firmware, I have installed the new Sonic Stage CP. But this soft didn't recognize the library of CP, so I had to erase all tracks from the A3000, import my tracks into SS4.0, and transfer it to the A3000. After that, the A3000 became very slow: when browsing in "Artist", it takes 2s to change the letter, and it is even slower to browse artist names in a letter... I'm a little bit angry with that... My A3000 became slower than with firmware 2.01
