Nad M33 vs Hegel H390... old question with a bit of a twist (ethernet and headphones)

@yyzsantabarbara Thanks for this. If you don’t mind, I have a follow up question. Our problem is that my partner needs to be able to use the headphones (while I am asleep 😂) with the TV. The TV could connect to the H390 via optical and use Home Theatre bypass. And we could use SPDIF to connect my IFI micro black label to the Hegel H390 BUT then the audio would come out through the speakers as well as the headphone jack. Defeating the purpose of using headphones at. Night.
Alternatively, if I hook up the TV to the Hegel and do not use HT bypass, then we will have to use the manual volume control on the headphone amp. Which is inconvenient as the TV and equipment are about 15’  from the sofa. 
I am totally happy to buy a new headphone amp at this point (already over budget anyway) but just need one in which I can connect it to the H390 and have a separate volume control remote for the headphone amp. 
Maybe I am missing something..... Thanks in advance.
p.s. Am going to re-run Cat 8 cables to the media room as they are better shielded.

@jjss49 and @badgerms Thanks again for all of your advice. This is what happened during my visit to the dealer in Vancouver. We started with the Hegel H390 hooked up to JBL classic speakers (in the $3300 CDN price range, same as my KLH m5). Sound was amazing, but it was the timing that struck me most. The music was controlled but with an underlying tension and restraint. Then we listened to the H190s with $20K speakers. Good but different and I was still torn. So I asked him to move the H190 to the same rack as the H390 and we alternated between the two with the same songs (would play half a song on the H390 and the other half on the H190). The dealer was very patient as he changed the speaker connection between the two units for 2 hours. He said that he had never done this before with the H190 and the H390 because usually customers are looking at one or the other. The differences were profound.
Here is what I noticed each time. The H390 had completely different timing, it was fuller and richer and felt like the music was immersive drawing me in. We would change back to the H190 and suddenly the same music was lively, faster but thinner in depth (don’t have the right vocab here). Every time.
The H390 felt like something I could never go back from. If I had not heard the H390, I would have been happy with the H190. But that door was closed. 
Luckily for the dealer, I had to catch my flight back to my small town so bought the H390. 
I am waiting for him to ship the unit after we figure out the headphone jack strategy (see post above in response to @yyzsantabarbara ). No way would the little coastal propeller plane allow me to travel with the Hegel 390 anyway ... Probably heavier than most passengers...
Thanks again.

@atanarjuat99 Congrats on the Hegel. I was asking the same question at Head-fi.com then realized I do not want to connect the headphone amp to the integrated because of the volume control in both. 

This is what I would do in your  situation. Buy a cheap DAC around $200 (since using with only TV) and get 15 feet of optical cable (amazon). Hook up the DAC to your existing headphone amp and then snake that optical from the TV to your DAC. I have about 10 -15 feet of optical running from a computer to my DAC and it works well. I use it for TV sound when I watch streaming sports.

op

you are correct

bent holter at hegel made a conscious decision to voice the h390 and h590 to be ’richer’ sounding than the lower models, which persist with the well known hegel very clean serene transparent rhythmic sound... hegel makes what i believe to be an excellent commercial judgement that a good many more wealthy buyers may be older and/or have more refined tastes in the hobby, and want a smoother warmer (full fat vs skim milk as john darko the reviewer aptly puts it) sound, as the gear is often paired with very expensive high end speakers that generally provide a little too much treble energy (magico, focal, wilson and so on), esp. paired with digital -- so think of it as hegel giving you a more tubey presentation (albeit with all the benefits of solid state bass control) without the tubes in their upper tier models...

glad you found what you like and it shows what an excellent careful demo provides in terms of certainty and confidence on the part of the buyer - enjoy!

Hi. I am also looking for an all in one solution with hdmi. Has anyone compared the m10 and the lyngdorf tdai 1120 and the arcam sa30. I have Sonus Faber bookshelves
