New TT or upgrade cartridge/platter on Project DC


Quick backstory: I purchased a Pro-ject Debut Carbon with 2M red cartridge around Thanksgiving to start my vinyl journey. I didn’t want to go overboard to start as I was unsure of my interest level. I’ve been strictly digital prior  playing MQA files through a Bluesound Node 2. Since then I’ve quickly accumulated over a 150 records mixed of my favorites and a large stack or original 70’s pressing who my father passed down which I had no idea where hidden away all these years (I’m 34). 
I’ve fallen in love with Vinyl since and I’m at the point where I know there is so much more to be had to improve my listening experience. I’m very happy with my entry level audiophile system and am looking for some recommendations on where to go from here on my TT? 
My system for reference:
McIntosh MA5200 integrated
McIntosh MR-65B tuner
Pro-Ject Debut Carbon tt
Bluesound Node2 digital 
Sonus Faber Venere 3.0 speakers
Nordost Blue Heaven Power Cord/Speaker Cable/interconnects
Do I upgrade to the acrylic platter and move up the 2m chain Blue or Bronze (would be $4-600 for cartridge/platter alone)? 
Do I just sell my Debut Carbon, save the $ on the cartridge/platter and upgrade my turntable? 
I would like to here suggestions and ideas, let’s go with a budget of $1,500 for conversation. I really prefer going the pre-owned route as I’ve been able to find some really great deals on here over the years on almost all of my equipment.

@aasteven111  - I have a similar TT to you. Mine is the Pro-Ject Debut Carbon Esprit SB. It is based on the same TT as yours, has the same arm and cartridge. Only difference is mine came from the factory with the acrylic platter and it has a speedbox electronic speed control.

I enjoyed it for a while then did a couple of upgrades. I replaced the Red Stylus with the Blue Stylus and I upgraded the phono cable to an Audio Sensibility Impact SE. Those two upgrades did make a pretty significant improvement to the SQ. I also did a complete alignment/setup to insure the setup was optimal.

Although I enjoy my table very much (and every day!) I don't think I would invest any money into a Debut if I were looking for improvements. The platter, stylus and phono cable would cost you another $400+. I think I would sell the Debut for whatever is the going rate and look at investing the (up to) $1500 into a higher end TT.

My TT is a good sounding table, very musical and enjoyable, but a bit noisy. I was considering the upgrade to an Ortofon 2M Bronze, but I think I'll do that upgrade on a different table. One that has the ability to pull out more performance from the complete setup.
The pro-ject classic evo with the quintet red moving coil would be a nice upgrade. Although the north American model comes with a sumiko amethyst moving magnet...found out the hard way and returned it. It was falsely advertised as coming with the ortofon. Still a nice table. I ended up just sticking with my good old pro-ject classic sb with my hana el. Also have a quintet blue in the wings to try. I did upgrade the sub platter to the aluminum evo subplatter and added a hide in the sound mat in dark purple to compliment the hana in moss green. This up against the eucalyptus plinth looks lovely.
I was in the same situation, I have a vintage Dennon TT and was considering a new TT. After doing much research, I found the most reasonable solution was a better cartridge. I changed my Grado Red 2 to the Ortofon MM Bronze and it has probably been the best upgrade so far.
Use what you have.   With a collection of 150 records, it's not worth the expense.  I am old and most of my records were purchased when they were the only thing.  If I were starting out today I might buy a turntable such as yours just to play around with a bit. Going whole hog into vinyl in 2020 isn't worth the effort. Unless you are in love with music recorded prior to the early 70's, digital is better in every way.
