That’s a pretty open-ended question. Given the price of the BB, I doubt if a very high percentage is the MQA license, and it’s apparently a pretty good DAC.
But what budget do you have?
Perhaps more importantly, what branch of epistemology do you subscribe to, rational or empirical? (Assuming it’s not skeptical, or you wouldn’t be asking.)
You may wish to review this discussion from last year. If nothing else, there are some nice cat pictures in it.
