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?

@david_ten Feedback is appreciated. Although if $2,500 buys a very good receiver, why can it not buy what I'm looking for if you remove the 7 (or 9 or 11) channels of amplification and all of the fancy video processing and Dolby/DTS/whatever audio modes?

Anyway, let's just remove the budget constraint altogether. Does anyone even make this product because it seems demand is there. I've seen quite a few people mention how the NAD C658 is the exact device they've been waiting on for years (myself included). So Mytek has something similar for $3k and Moon has something similar for $5,300. Are there any other options at any other price that are based on stereo not 9/11/16 home theater channels?
@dep14 I would maybe consider the Moon but I'd have to hear it in my home and have the option of returning it if it didn't sound amazing. Alas, there are no dealers within many hundreds of miles of me and I'm not taking a chance on a $5k piece of gear.
re: the HDMi from TV to the "Preamp/Streamer/DAC with MQA, Roon and more" unit, does your TV have an optical out?  If so, maybe you could run optical out of TV to preamp/dac.  That at least might get a troublesome item off your requirements list.  Just a thought.
