Actually, it does support high-res LPCM over DLNA, I've tested 24/48 and 24/96 to it just fine, even seamlessly goes from any bit-depth / sample-rate to another in a playlist. The SetNext bug interfered enough with my earlier testing it obscured this fact, as well as the unit not explicitly claiming the higher res support. But it is there. So even more pleased with it now.

They have done that, repeatedly and to my satisfaction. I am well aware of how this combination of process and format works. It is brilliant in its technical innovations, and a huge (and ongoing) effort in terms of industry alignment (which is where the risk lies). What they could have done better in terms of roll-out is what they are finally doing now, which is providing reviewers with direct A/B samples of source materials. see: An inconvenient truth: MQA sounds better! | DAR__KO But claiming they are keeping everyone in the dark about 'how it works' is incorrect.

Cebolla, thanks very much for the clarification and especially for the BubbleUPnP setting tweak, works great as well.

Gapless will never work with this unit, as the NAD claims to support it (AVT:SetNextAVTransportURI (gapless play)=Supported) when queried by the CotrolPoint (Asset or MC), but then totally screws up when it receives the SetNext command. What I get now is reliable sequential playback of long playlists, with a small pause between tracks. That fits my needs just fine, even though I do have a good bit of classical. So to get this renderer to reliably play L16/44 PCM, your ControlPoint needs to ignore the claim and never send SetNext. My posts in the JRiver forum show how to do that on MC.

To answer the original question: Yes, I'm waiting to replace my pre-pro until I can source one that handles MQA at the DAC level. My hope is for a Trinnov Altitude32 with MQA-capable DACs. I've been following MQA for over a year, and I am eagerly awaiting content and gear. This is revolutionary stuff, as correcting the temporal domain from errors introduced at the ENcode (master ADC) and also in the DEcode (the DAC) is the next quality frontier and requires a combination of process and a 'smart' container. The fancy folding is cool, but the payoff is the process and ultimately the dynamic adaptation to the MQA-certified DAC being used.

Resurrecting old thread to add some important info, as the Google has this thread listed as relevant for 7050-related searches. I have a new D 7050 and I'm on v1.66 firmware (latest as of posting date). First, the DLNA implementation is buggy, with the most serious issue being that it advertises that its capable of gapless play, but when feeding it uncompressed PCM, that's not true and it breaks badly. As described by others, the first track will play fine, the second track starts to get garbled and by the third it's just clicks. Once it gets to the clicks state, its hosed, and must be cold booted (power plug pull). After many adventures described in this thread over on the JRiver forum Setting up a NAD D 7050 Integrated amp / DLNA renderer with MC, I discovered that if one disables the 'SetNext' support in the DLNA server feeding this client, then it all works well. Still need to force the server to convert any source to 16/44 or 16/48. For instance, with stock Asset and BubleUPnP app, it failed with the sequence I described, but JRiver MC with that command disabled works perfectly. Asset might have a similar setting, haven't checked.

I love the sound of my new D 7050, it totally transformed a casual 'background music' 2.1 setup in my living room (I have a dedicated ultra-high-end HT and a secondary media room in the home, so my definition of 'casual' might be higher than most ). This is not a 'class D' digital amp, this is a revolutionary power DAC, or direct digital drive as NAD calls it, and due to its architecture, it can dynamically adapt to the varying impedance/capacitance loads of the speaker to deliver way cleaner power than otherwise. The fact that it has a built-in digital crossover for the sub is a huge plus. Note BTW that the 'sub out' is actually stereo on the two analog 'pre out' RCA jacks, so you must use a stereo to mono RCA Y cable to feed a single sub. The crossover freq. is selectable via the mobile app in 10hz increments between 40 and 200Hz. With all the network playback features, this seems like a killer unit, but I was pretty disappointed in its DLNA implementation which besides buggy is quite limited in terms of playback quality, with the highest uncompressed audio being 16/48. See my detailed adventures getting this to work right with JRiver MediaCenter at this thread Setting up a NAD D 7050 Integrated amp / DLNA renderer with MC But once all the settings are correct, it works very well with JRemote driving the experience. Airpay also works quite reliably. My unit is running the latest v1.66 . Here's hoping they rev it one more time to fix a few DLNA issues I identified in that other thread. All in all, a nice unit that delivers better sound quality than expected.

There is another option: DVD Audio Extractor http://www.castudio.org/dvdaudioextractor/ I've been using this and it works perfectly. Very nice single-step to go from DVD-A to multichannel FLAC files.
