Pandora vs. Pandora One. Any audible difference?

Free Pandora streams at 128kbps, Pandora One streams at 192kbps - which is the highest any commercial streaming service goes (i.e. Rhapsody). There used to be a few that streamed at 256k, but recent legislation may have limited them all to max 192k.

And yes, it makes a difference - especially on good equipment. Cymbals are cleaner, voices are a little more natural, and you'll get fewer compression artifacts popping up in the middle of songs (can sound like a bird chirping or a momentary speed change as something falls out of key).

Thanks for the response. I just started using Pandora and noticed those chirping sounds. I thought that it was a hardware issue with my system perhaps, but I see that I can avoid those sounds by upgrading.

I noticed a diff upgrading and for 3 bucks a month what a deal pandora is. (IMO)

I'm probably way behind the curve here, but Pandora was my best musical find of 2009.

I paid for a year of premium service and yes it is better and definitely worth it. For me, I was not willing to pay for Sat radio with there ("no commercial"---"COMMERCIALS) if you get my meaning. I use it in the home at work and on my iPhone. Pandora sounds great at 192khz. It's not bad at all at 128khz.
