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
-Preamp
-Network streamer
-DAC
-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?

Me thinks you have a bad unit, the Nad direct digital sound is anything but harsh, the NAD m51 a very good dac with similar technology we sold for years and it was very musical and not harsh in the least. 

What are you using for a power cord into the C 658? Any power conditioning? 

If you are using the C 658 into a Marantz receiver and then into a power amplifier that could be your issue. 

Something is amiss our C 568 combo with the Nuprime sounds really musical the Hegel H 190 was much harsher the Nad/Nuprime was really creamy sounding.

@audiotroy I only used the Marantz in conjunction with the PS Audio DAC since it needed a preamp to be most effective. The NAD runs straight into my amp. Power conditioning is from a PS Audio Quintessence and the power cord is a Pangea AC14XL Mk II that I recently picked up to test out. The power conditioner is plugged into the wall in a PS Audio Power Port outlet.

Not sure if the Altair has the bass management. The Vega G1 is really good. Many reviews of it and the original Vega. 
If you currently have the PS Audio dac, keep it, you won’t find anything better for anywhere near its price. Since this covers a few items off your checklist, now get a preamp that handles the rest of your wants. 
Btw: the ps audio ds dacs do sound better going thru a preamp. I have 1 and tries both setups
