Does this exist? Preamp/Streamer/DAC with MQA, Roon and more

I'm looking for a particular set of features that seem to be very hard to find in a stereo (2.1) product. My budget is preferably around $2,500 but there is some flexibility. Here's what I would like:

Must have
-Network streamer
-Roon endpoint
-MQA compatible (not interested in your opinion of MQA)

Want to have
-HDMI inputs/output for video switching only and 2 channel audio (to allow TV sound through stereo)
-Room correction
-Subwoofer management

I recently purchased the newly released NAD C658 which, when adding the optional HDMI module, covers every must have and want to have (Dirac room correction is coming in a later FW update) for a total of $1,800. Perfect! The problem is that so far the thing sounds lousy. I'm trying to let it burn in more and see if Dirac comes and makes it better, but it's not looking good after the first few days. The DAC seems to be the problem. It seems to suffer from audible time smearing and sounds too clinical and harsh so I am suspect about Dirac helping with that.

I've also seen the SimAudio Moon 390 but it's $5,300 and doesn't have room correction or subwoofer management. On the less expensive end, SimAudio also has the Moon Ace for $2,900 which has the same features as the 390, minus the HDMI inputs. I'd use the preouts to my own amp since the Ace is an integrated amp.

Then there is the Aurender A10. It costs even more than the Moon 390 and doesn't have HDMI inputs.

Cambridge Audio has some well regarded streamers but they aren't Roon compatible.

Finally, there is the PS Audio DirectStream and DirectStream Junior. I recently purchased the DSJr since it can be had close to my budget and while it sounds incredible as a streamer and DAC, it's not viable as a preamp. I spoke to PS Audio about this and they recommend using a separate preamp for the DS and especially for the Jr. I can't remember exactly why but they told me the signal to noise ratio when used straight into an amp wasn't ideal. I tested this myself and found that the DSJr sounded better even running through a Marantz AV receiver as preamp than it did straight into my amp (the receiver uses pre-outs to the same amp). I don't want to run a DSJr through a Marantz receiver and if I blow the budget on the DAC, I won't be able to get a capable preamp worthy of mating with it. Plus I'm really trying to get down to fewer boxes.

Are there any other options out there that I'm missing?
You already tried your solution:

" Second, when I connected a PS Audio DSJr through a Marantz AV receiver as preamp, then to the exact same Musical Fidelity amp and Monitor Audio speakers, the sound was GLORIOUS in comparison to the NAD"

You don't need amplification so a Pre-Processor would be ideal.  Marantz Pre-Pro are readily available, both new and used.   7705 from Audio Advisor:  $2199 NIB    FYI-  Kalman R was very surprised by the quality of the DAC in the next model up...8805, stating that it took upwards of $5k in external DACs to improve digital reproduction.

@iopscrl Perhaps you are right, it just seems silly to buy an 11.2 channel processor with all kinds of fancy processing to end up putting it on Pure Direct mode the entire time and use only 2.1 channels.
@rbstehno I'm gravitating in that direction. I already sold the PS Audio DAC but could buy another one. Interesting that their other preamp (the Stellar, I'm not counting the BHK due to budget) is also a preamp/DAC, so I wonder if that one really does work well as a preamp or not.

@drumnman2 Do you own the 658? Any listening impressions?

@golfmatchplayer The Oppo 205 looks pretty good but is discontinued and now people are asking 3x the MSRP for used ones. At the moment I don't really need any analog inputs because all stereo listening is through Roon streaming and TV audio is HDMI through a few sources (Bluray, Roku, Chromecast) that would probably just all be fed to the DAC from the TV via a single optical cable. Having an analog input or two would be nice for flexibility but isn't a requirement right now.
Another vote for the Ayre QX-5 Twenty. If you can find a used one that fits your budget you won’t regret it.
