Hi I too want one. Saturday I bought my friend a F&D 520 after reading all positive reviews on Flopkart and other websites.
I donot like the sound at all. I played Give-It-A-Go-feat.-Veronica-Timbaland and the bass was very distorted at high volume for this song (same mp3 file). I played from Laptop and SE Live with walkman, Bass is distorted. But when I play in my Sony Hi-Fi I get clear sound.
So suggest me a good 2.3 with tight bass.
