For those interested, I reached out to Topping last week to see if they could give me a release date for the DX7 Pro and here is their response:

"Thank you for your mail and sorry for the late reply!

DX7 Pro is now being adjust for better performance, which need a lot of time to finish. We expect to finish and released it on August. Sure our sellers will put it to Amazon later after our released."

Hopefully it will result in a better outcome. They did something similar with a massive delay to the D70 Dac (I'm surprised it didn't perform better, but nonetheless, a great DAC, though the price is a bit ehh at the original MSRP).

This thing it looks like they're having more trouble than first anticipated, getting double troubled by the dreaded ESS hump (of which some DAC makers have been able to smooth over heavily to basically make it look as if it doesn't exist). But perhaps they're having luck compelling ESS to bring out some revision with silicon-level remedies (seeing as Topping said if I recall correctly, the ESS Hump is a hardware flaw with no software mitigation).

The second thing that seems to be delaying this thing is the DX3 Pro's sensitive opamp perhaps that have led to more than a non-trivial amount of failures of the entire device (as one user reported being offered a fix where the replacement resistor will raise the output impedance to a horrendous ~15ohms).

Regardless of the issues, it looks like they're taking the problems seriously to have delays of this length.

I just hope they go easy on the price premium (as they're seemingly trying to move up the pricing pecking order quite fast as we've seen with the D70). Nonetheless, I've wanted this device when it was first revealed. Though it's going to take quite a bit to get this RME DAC off my hands >_>

Well, I do think they more or less squeezed out every last bit out of the AKM4497 staying under $500. Now to wait for AKM4499 devices.. :)
The Yulong DA10 for example is marginally better but twice its cost.

Any ideas of the probably MRSP ? 1k$ ish ?
For what? 4499 Devices? Far far more than $1K I'd say, its a pretty big hardware shift and upgrade in terms of the schematics it seems. Capabilities, and work around the chip seem like it will take quite a bit of work to squeeze the best out of the chip.

They already have some competition in the form of Sabaj DA5, although the Sabaj doesn't have bluetooth and the headphone amplification seems inferior on paper :

So sure they will increase the price compared to DX7S, but up to a limit, and if it's worth will of course depend on performance for the final product, a pre-production unit according to Head-fi had a measured SINAD value of approximately 107dB, but anyway it's likely that Topping will send a production unit to Amir for review, so let's wait and see how it goes.
