Beginner choosing amp help

I would suggest Aurender N100H as the digital source for streaming Tidal with the Luxman.  But the Luxman does not have an internal DAC, so you would have to get an external DAC.  If you want an integrated amp with internal DAC, then I would suggest the Hegel.  Also, a good USB cable like the Curious really makes a difference.

As far as vinyl to be honest I’m still not too sure how far I’d like to go with it.I’m just getting into it and still in the process of experimentation with it and deciding if to my ears vinyl sounds better then the high quality and lossless audio formats that Tidal offers. It’s just vinyl seems to be so expensive new also lol.

Well you get what you pay for.

And- "high quality and lossless" with "Tidal" in the same sentence! Talk about LOL! LOL! Let me guess: you weren’t around for "perfect sound forever"? https://www.stereophile.com/asweseeit/656/index.html

The best records by the way are not necessarily the new ones. First, because almost all the great music out there is old. That just stands to reason. In any years time only a tiny fraction of music is any good. So almost all the really good music is old. Combine that with the extreme care they used to take to attain the highest sound quality. Throw in the wild card that any pressing new or old or however well recorded, to sound good on vinyl you have to find the copy that sounds good. Meaning in other words no two copies sound the same. Put it all together, a really good copy of a really good recording sounds so freaking good you cannot believe it. And most certainly you cannot come anywhere close anywhere this side of the original analog  master tape, "lossless" "perfect sound forever" notwithstanding.

But it also means a lot of vinyl is dreck. I do hope you are paying attention? Digital is not about quality. The only two things digital has going, convenience and consistency. You want to find out real fast if vinyl is worth it? Go to Betterrecords.com and buy something. Then you will know. You can always send it back. If you can stand to do without it. Once you hear what is possible you will never be the same again.

Meantime you want to be listening to tube integrateds. While you are at it be sure to listen to speakers. You need to listen to a lot of stuff because that is the only way to figure out if its better to limit yourself to an amp that can drive what you have, or upgrade speakers and amp in one fell swoop, or whatever. Reviews and comments are only very crude filters. You need to get out there and listen and compare as much as possible. Next to listening to a White Hot Stamper its the best way to spend your time.

Get an integrated amp with a nice dac and network streaming capabilities. You can find some that are roon ready and then you can just plug Ethernet in the amp and your computer can send tidal right over WiFi, into your network, and into the amps DAC.
 LUMIN M1 or something like that. I thank NAD makes one. And possibly McIntosh Ma5300

Some good thoughts above. You will need to decide if the ML Motion
is a long term keeper or a likely future item for upgrade. Best advice
is to read, listen and learn. Your preferences may change the further 
you get into it. Good luck!

Having auditioned both Luxman and Hegel integrated amps recently, Imy opinion is that both would provide noticeably better sound. Your speakers are 4 ohm and the manufacturer recommends amps with 20-300 watts power. That’s an overly wide range and I would recommend erring on the side of having more power, especially given the 4 ohm impedance of your speakers. Hegel amps are real powerhouses, and the H190 at 250 watts at 4 ohms would be a good fit. While at $4,000 it is a bit over your budget, it has the advantage of having a nice DAC as part of the package and it has an Ethernet port. My dealer indicated that certain Hegel products should be designated Roon ready in a matter of months. Purchasers of units before that upgrade will be able to download a firmware update to make theirs Roon ready.

Audition one at home (and some of the others recommended) and listen on your speakers in your room. That’s been my rule for many years and it has served me well. Dealer showrooms are often treated with acoustical panels and can sound dead compared to a listening room in a typical house.
