ohh this is interesting
Very nice amp indeed. Go ofr it @JamesFiiO
BB (like iDSD micro) or ESS DAC (like 901s) is great, both can deliver astounding sound quality, I have the iDSD micro and boy does the dual BurrBrown wonders in it. However it's the implementation that counts. At one stage we pitted 4 different AKM Inside DACs against each other and they couldn't have sounded more different.
Or you could consider the AK4490 from AKM as in the new Astell & Kern AK380?
I like the Hifiman-esque amp boards a lot....

@JamesFiiO, why are you concerned about power for the ESS9018K2M? I thought that was designed for low power use?
I would think he means dual 2ch k2m's or single 8ch ess9018. Which is better for power? There was a lot of discussion in the X7 thread about it quite a while ago. Then again I'd also like to know JamesFiiO's reply to this.
Like the combo of both world- analog and digital vol controller for precise control.....Hope there will be display if there's wifi.
@JamesFiiO: how about adding AKM / BB DACs?
I'd like to see a good gain control with 3 gain positions or at least the LOW gain with 0db, otherwise another amp/DAC barely usable with iems.
Sharing plug and play amp modules with the X7 will have three choices........ an IEM amp module, a high powered amp module (500mW), and a more powerful balanced (RSA) amp module.
This is the amp module (circled).
And on the X7.
we will release a lightning-Micro USB cable in the coming soon which supports all the USB DAC. so it is not a problem now.
of course, the target price has not decided yet.
in our new design, the low gain will set to -2dB. we will see if we can design a 3 gain control in it.
AKM is also an option too. maybe the same in AK380, lol
Ooooooh. Gain control with amp modules?
Could be a great idea.
of course, the implementation is as important as what DAC chips is used. but the fact is the expensive model always used the expensive DACs, even in HIFIMAN, AK, and SONY. to be honest, part because marketing .
BTW, it does not need any display in Q5 because all the control is done in your iphone/android phone/ipad/Laptop. did the wifi router need a screen ? lol
