Actually Sabre Dac is not the best solution for DAPs. I would take a look at PCMs or AKMs.

Why?  I personally didn't like the mobile ES9018 on the DX90, but the non-mobile is nice, but probably turn out bulky if implemented for portable use.  This is why the 901 and DX100 are so huge.

Because Sabre sounds very synthetic. Compare old-school 801 and DX100. The first one sounds fuller and deeper.

801's output was contrioversial as it rolled off like a mutha.  Implmentation was piss poor.  X5 was flat and Cowon P1 is trying to implement it, and waiting on impressions.

Yes, I agree, that 801 lacks a bit at high freq, but the mount of details is still the same, like in dx100 or 901. but the whole sound impression is so, that it sounds a lot more fuller. It sounds "massively", like some really "big" DACs. Because of Multibit dac.

And this Graphic is not the most important thing, when you speak about real SQ.

The treble that actually matters are from 6-10k, I think they blatantly filtered to make it sound warm.  Look at it, if you reduce the treble, it will turn warm.

The same roll-off is more or less still on HM901, and everyone I know who have heard it is praising its SQ, including some A&K fans. HM801 might not has the best implementation, but it is the best of its generation IMO and same can be said to HM901 when it comes to pure SQ. So don't judge the book by its cover. Also on extra note, that roll-off can actually be found inside ES9018 / K2M, and it is called the "slow roll-off" digital filter. If it is pointless, ESS won't have included it into the hardware design.
 
To put it simple, every design choice has its pros and cons.

I wanted to say, that in Multibit dacs you hear the sound as one unique, flow. In Delta Sigma it has some portions: here is bass, here is tremble and it doesn't have any connection with each other. But in Case of Multibit. The sound is like a huge Flow. And i like it

Sorry here ,am a new to audio.Is it possible for wm8740 plus es9018m2k together>?

It's possible, but not for the same type of audio format --- if you have a separate processor such as a uniquely designed FPGA to process the I2S dumuxing process, and send DSD to the ES9018K2M, but PCM to the WM8740, or even 44.1/48 to the WM8740 but bitrates higher than that (88.2 - 384 kHz, plus 2.8/5.6 MHz) to the ES9018K2M, it's totally possible. However, it's also probably necessary to also design two separate analog signal paths as well.
 
Basically, it's a huge waste of money and not much value to the consumer, unless the implementation shoots for a "money is no object" paradigm, in which case you wouldn't use a WM840 or ES9018K2M, either.
