DAC's Made in the USA

I do think Schiit is your best bet.. But Schiit does not support DSD and your SACD (SACD LAYER) will not work with any of these DACs due to copyright implementation back in the day.  I think the only way you can use an external DAC with SACDs (SACD layer) is IIS (usually via HDMI type of connector) and even that is a bit of a wild card and I don't have any experience with using external DACs for SACD layer.  

Another possibility is PS Audio's DAC that support SACDs (DSD) I think but that is north of $6K.

There is also several R2R DACs (vs Delta Sigma) that supposedly sounds amazing per reports and one of the most popular one is sadly, Made in China (Denafrips) but sold by a Singapore dealer exclusively (Vinshine Audio).  Vinshine's owner Alvin has confirmed that Denafrips have no Chinese Communist Government ownership, rather, it is owned by a single proprietor. So...  

I too have the same objective of sticking to Made in USA, (but in my case, with the constraint of "without breaking the bank").  So I ended up with Schiit Mani (phono) and Modi3  (DAC).  My integrated amp is 100% made in USA tube class A (and happens to cost 3X comparable China made ones).  My speakers are Klipsch Cornwalls.  But alas, my CD/SACD players/Streamer are either Japan or Malaysia or China.   Not much I can do there without shelling out much much more $$$.

DAC technology changes a lot too so that's another point to consider in as far as how disposable they are.

AND then,  I started questioning myself if my MADE in USA objective truly accomplishes what I want.... which is not to support governments that are not our allies or more importantly, hostile to us.  I concluded that I don't know... as if I truly want to send a message to Chinese government  (and frankly, American companies that decided to set up shop there), we should also shy away from 99% of Apple products, 99% of HP/IBM/Lenovo/Dell products, just about all smart phones etc..  AND, I don't see that happening at all as I don't know what practical alternatives we have with these devices... .And I highly doubt is the Chinese government has much interest in DAC companies which is more like a cottage industry compared to Huawei / Alibaba etc.

Our beloved world of hi-fi audio is rather minuscule  as compared to Apple / HP / Dell's operations in China.

As the world turns !!!  

OP, if you bought a piece of Chinese gear -- but used, from a fellow American -- you would be helping out someone in your country without adding profit to any companies you don't support. Maybe that would help find the right gear without some of the ethical costs you're concerned with? Just a thought.

This is what many may regard as an off-the-way suggestion.  But here it is, anyway:  you might consider selling the Sony universal player and buying a used (only because they no longer exist new) Oppo 105 universal disk player.  This player has excellent high-res DACs built in for the disks, and also has built in inputs for both Tidal and Pandora (streaming).  But the real reason I would recommend it would be that if you added a low-cost internet "tuner" (which the Oppo would take into its own DACs) you could also take advantage of the numbers of internet radio stations playing jazz and blues music .... thus creating some new experiences in your arena of preference.  The "swap cost" and the internet tuner could probably fit your budget.

BTW, I'm also 80yr old, enjoy the same music, and have a similar Oppo setup, except that I don't yet have (or really need) the internet radio because the local NPR station (WFCR, Amherst, MA) is already has some of the best jazz programming in the nation at night between 8:00 and 11:00pm plus a wide array of jazz podcasts.

As I said, off the wall ..... but I hope perhaps of value.

A tad bit above your price range, but If you do nothing more than read the overview... it’s worth it.
