Best significant upgrade? Dac? Preamp?


Hi guys!

Im hoping some of you with knowledge of my system can help me make a good decision about my next upgrade.
I would like a surprising and obvious difference not hard to spot subtle change.
From my research i think the next move should be the Dac.
I would like to explore DSD,i have some SACDs now.
my system:
Mark Levinson 320s preamp
(Would i see a difference with a ML no.52?) I am also looking at the no.52 ,would i see a big difference compared to the 320s? Worth the extra $$ ?
interconnects: Acoustic Research master series silver high definition RG6
ML 431 amp
XLR: +bo ? +ba ? Only info on them

Wilson Audio Watt Puppy 5.1 speakers (serie 7 tweeters) +transparent music wave plus cables
Arcam rdac (wifi) with Teddy Pardo power supply.
Running on mac air (usb) ,Tidal HIFI
(i currently listen most of the time to this vs rarely SACD).
Thanks!

I switched over to analog for my critical listening about a year ago, so I'm satisfied with the DAC in my Classe Sigma SSP for my casual (i.e., multitasking) digital listening. But were I looking to upgrade the digital side of my system today I'd seriously look at products that support MQA.  As I'm not looking to upgrade that side, I haven't taken the time to verify the "game changer" claims I've read in many reviews of MQA and supporting DACs, but I'd certainly look into it.
