Jamkazam is moving onto Paid Subscriptions. Donors and volunteers' thoughts?

[DaveK]

Is there a discernible difference between the Free plan Audio Stream Quality rate of 128 kbps vs. the increasingly faster rates that come with the higher level subscriptions? I am especially interested in whether or not I will notice a difference between the Gold rate of 256 kbps and the Platinum rate of 512 kbps. 

Can anyone accurately describe the trade-offs in performance in terms of my individual experience, and my combined experience, assuming that the folks I am playing with will be at different subscription levels?
