you can make a 16 bit R2R ladder using a bunch of resistors
Theres got to be a cheaper approach to even the one RazorConcepts presented.
you don't need that kind of precision.
resistors from the same batch are precise enough to be used for such a purpose (try testing them with a good multimeter and see for yourself)
8 bit is fine for some stuff, but it's not fine for music. For example, in a drumbeat, you need crashes and cymbals, which are white noise with a timbre, so to say. With only 8 bits of resolution, a cymbal will sound very bad - try it.
This wave shield is interesting. The sampling frequency is kind of misleading though: is the 20k the sampling frequency (meaning a max of 10k - thus, not very different from ISD chips, which adafruit bashes) or is the 20k the max rendered frequency (and thus, the sampling frequency is 40k ) ?
The drawback is that you can't get high pitches. If you go with high sample rate (20khz), you'll need a pwm frequency of 40khz,
