First off, I'm about as much of a DIY audio builder as I am a bronze sculptor. Secondly, I recently bought an enclosure from dsavitsk that has some parts in it that were once a DAC. Specifically, it needs a 12AX7 tube and a CS8412 chip. The tube I have already of course. I did some shopping on the 'Bay and found what I believe is the right DAC chip for $6 from a Chinese seller. The rest of the iterations mentioned in this post are strictly for academic purposes. I'm genuinely curious what the differences (if any) are.
The version I bought.
CS8414CS for $13
The main difference here is that this one can speak hibit (24/96) and purports to have lower jitter. I assume that in order facilitate high bitrate playback, the rest of the digital circuit would have to support it as well?
DIR9001 to CS8412 or CS8414 Pro Version Converter Board for $70.
This is either serious business or an enabler of audiophilia nervosa. Look, it has capacitors on it!
My question is this: What are the realworld differences between these chip iterations? Is there something major I'm missing? Would there be any detectable difference in them when placed in a circuit designed to use a CS8412?
