DAC upgrade?


Hello, I was hoping to get some insight and opinions on upgrading my DAC. I currently am using a Rotel A14 integrated amp and am using the internal DAC of the Rotel. I can't seem to find any specifics regarding the DAC other than its an 

AKM 32-bit/ 768kHz Digital to Analog Converter. The amplifier is powering a pair of Totem Staff speakers and do most of my listening with digital lossless media (ALAC, FLAC) output from a Mac mini and using Audirvana.

I certainly do not consider myself an audiophile but I do enjoy good sounding music. Do you think upgrading my DAC would be beneficial? I wasn't wanting to spend too much on a DAC but was wondering if something like the Schiit Modi multibit, Topping D50 or comparable would provide a better/different sound?


Thanks in advance and look forward to your comments.

I’d think you’d need to move up to something like a Gustard A18 ($560) to start hearing significant improvements — and that’s just a semi-educated guess — but as a casual listener I’m not sure it’d be worth it and probably best to just stay put for now.

If you’re mainly listening to your own music, then by far the best upgrade you could make IMO is to try a Qobuz account and open up vast new worlds of hi-res and CD-quality music through streaming.  It’s the best 13 bucks I spend each month.
After a quick search, there does seem to be some good reviews on the Gustard A18. There also seem to be comparisons between the A18 and Topping D90.Any thoughts regarding these two DACs?
The guy at soundnews.net does nice reviews IMO and has reviewed both as well as the A22 and may have even done some comparisons between them.  Again, I do believe you’ll get some improvements, but changing DACs isn’t like changing speakers so whether it’s worth it depends greatly on how casually you listen.  If you sit down to listen to music this could be worthwhile, but if you usually listen while doing something else it’s probably not.  That’s about the best way I can put it.  Hope this helps, and best of luck. 
@soix Thanks again for your responses. I would definitely say I am more than a “casual” listener as I like to sit down and will listen to an album start to finish. I don’t, however, find myself critically listening when I am listening to an album.
Regarding one of your other comments, would my personally ripped CDs into lossless FLAC/ALAC sound just as good, if not better, than streaming cd quality tracks from Tidal/Qobuz?
