Would I be wasting my money to get a turntable?

Hello Frit, your question is, should you get a turntable even though the signal will be going through a class “D” design. So it passes through digital.  1st thing you note, even thought the analog signal will pass through a digital format, you will still hear the difference of the sound of a turntable. Of course, if you could keep the signal 100% analog, that would be the best way but if it does pass through a digital format, you will still hear much of what the sound of a turntable does.  I think the biggest question to ask is if it’s worth getting a turntable setup. I owned some of the most desirable items in hifi and I have 2 vinyl setups. Do I really appreciate their sound? Yes I do. Do I listen to them a lot?  Not really because digital is faster and easier to get going. I would recommend to anyone that if they want to hear great music, they don’t need a turntable setup. But if someone is looking to expand their system and try to get even higher quality playback, then they could explore vinyl. But vinyl is also a totally different and very complex setup to get correct. 

The M33 is a nice piece of equipment.

Get a turntable if you want one, especially if you already have records or are interested in buying some. Playing and collecting records is fun. The cover art is fascinating and the liner notes are interesting (and big enough) to read. The sound will be fine (and probably improved by the digital trickery).

For your system I would recommend a Rega or Technics turntable (there are others that are just as good but this is a good starting place). The advantage to the Technics is the changeable head shell, allowing you to easily experiment with different cartridges.

Go for it!

Sorry for your loss. There is not much that compares to losing ones mother. I hope your new venture down the vinyl rabbit hole brings you the peace and closure you seek.

I agree with "grislybutter" BUT I would ammend that with at least $3,000.00 and definitely put more emphasis on fiddling or tweaking. It's definitely not a sit and press the remote thing.

I had an fairly inexpensive audio setup when I decided to get rid of my 100 or so albums and inexpensive turntable. An article by Michael Fraemer made me decide to take another look at analogue. The first thing I did was buy a better cable from the turntable to the preamp. It helped a bit, but I'd be lying if I said it sounded better than CD. Then I bought a used Rega 3 for about $500. (This was mid-nineties.) Also a Sumiko Blue Point Special. I began to hear a bit of difference, especially in the Rega's speed as a result of its glass platter. 

Fast forward through buying about a thousand albums and upgrading eventually to a VPI Prime Signature and Audio Research PH-7 with an EMT HD 006 cartridge, about $2,500 worth of gear. Now the main difference I hear with records is air. Even digital through my streamer at 192 resolution, which is damned good, lacks the air and warmth of a good analogue setup. 

My main point is whether you feel committed to investing in analogue even though it might take a long while to upgrade your system, and even when you have upgraded, to be able to hear the difference. I guess my suggestion would be to visit an audio store or a friend who could demo a good streaming system versus a decent analogue rig. See what your ears tell you. Can you hear enough difference to invest time and money?
