Have this and served me very well: Singxer F1. Bit on the expensive side since it has USB isolation, Crystek Femto reclock, and CPLD shaping.
Available at ShenzenAudio or Kitsune

If you can go optical you are isolated, just to mention. That Singxer is nice though.

Anything Non-AliExpress that does the job IMO. There's a recent headline why are so many young people getting Cancer these days. Please be careful what you let in your household.
I posted Reddit links about headphones and electronics w/ Cancer issues in another thread. I liken it to like Fetanyl. But Reddit sub-reddits are blacked out ATM.
The way I see things is a NUC with optical is $400, spread out over 10 years that's $40 / year. When you buy these cheap goods, you need to replace every two years. So you buy some cheap knock off that's $40 that's $20 a year. Over ten years, that's a good $100 over a decade.
But this NUC solution is too complicated. A Western brand may need replacing three times over ten years. There's nothing quality we are offering to the THREAD_STARTER, they are all bandage solutions. Apple put loyal users in a bind. Maybe a modern DAC makes more sense if it starts to become too much.

I just remembered another possibility. I haven't looked into Computer Monitors or Televisions for decades since I've been overseas in that time. But I remember some Computer Monitors or Televisions have Toslink Output.
So if you purchase a Mac Mini, Mac Studio or Mac Pro with HDMI output, you should be able to get a digital signal via HDMI from Mac Hardware then feed your old legacy DAC from a Computer Monitor / Television via Toslink OUT. You may need to enable Toslink in the Computer Monitor / Television settings.
I believe this is similar to Apple TV | HDMI | Television with Toslink | Toslink | Home Theatre System. Again, been overseas so I haven't built a Home Theatre System for decades but I would think this is how some would architect, even in 2023.
I can't confirm if this works since I don't use Mac Hardware, only MacOS Software.
Note: You need to be comfortable with purchasing non-proprietary non-Apple HW (Computer Monitor / Television). Apple won't have a external monitor option.
I'm sure some place like Best Buy would be happy to try this out for you since they have both Apple HW and Computer Monitors / Televisions.

I bought this when I was trying Apple Classical. Worked flawlessly.

One option would be to purchase a 2014 Mac Mini or 2015 iMac. The downside is that you would be locked into the Monterey operating system. Obviously, it would be slower than a newer computer. Judging by the fact you are still rocking a 2008... I'm guessing that's not an issue. That involves the least amount of disruption to your current system and doesn't involve adding any converting devices. Might be the cheapest option too--the price difference between an older Mac compared to new is significant.
