Mola Mola Tambaqui Roon vs Separate Streamers

good stuff @yyzsantabarbara ! Thanks.

What do you know of the new products by Master Fidelity, the Nadac D and Nadac C?  Reviews are over the top.

@fastfreight I have not heard anything about those 2 new DACs. Now I have something to read while I waste time at work.

@yyzsantabarbara 

Very interesting history.  I use FPGA chips (maybe even the same chips; that's how flexible they are) in certain industrial applications related to the oil field. They are great for small scale production because you can use the same chip lots of different ways and (as the "field" part says) alter them for bugs on the fly even after deployment.  Very useful for prototypes, too.  This is why a lot of high end audio people use them -- there are just not that many units being sold, so a custom-designed chip is not practical.

The problem with them, however, is they are general purpose.  It's like a a really good adjustable crescent wrench. It's excellent and can be used for whatever, but just isn't as good as a wrench or ratchet just for that particular bolt.

I'm not joking that I probably use the same exact chipset in a giant rotary directional drill that is used in a nuclear missile, the Nagra HD DAC X, a Lamborghini, and your favorite bespoke DAC.

They are also energy hogs, hot, and (with some exceptions) very electronically noisy.  All that can be compensated for, but can poise problems on implementation, especially in audio equipment.

Anyway, long way of saying, all things being equal, I'd take a custom chipset over a FPGA set, any day -- assuming I have a chip set that fits my bolt, so to speak (which is a giant assumption, as that may not be practical when you make 100 units of something).
