At least mine died quietly, without fuss.
The replacement is not 24h connected luckily but it gets very hot as well, with and without the PSU in.
I don't see anything new as well but I would trust more Archimago's measurements which are a bit different:
A blog for audiophiles about more objective topics. Measurements of audio gear. Reasonable, realistic, no snakeoil assessment of sound, and equipment.

I understand what he means, I like as well more the DSD output; but I don't think there's any magic behind.
In my opinion, the DSD output is the "NOS Mode" for the DAC-poorers

The DSD is more "unfiltered", not really but filtered differently, and I guess this can be more enjoyable to some ears.
I have the impression it's not only me but also my amp that likes it more, I never tried with something else thou.
Also, maybe with high-end DACs there's not much difference but on low-end devices, like the Topping D50s, it's a tad better than PCM.
I kept using it also with the Aune X8 and the Fosi ZD3; they have a better PCM output and it's impeccable but it's not the same.
Even if technically the signal can get worse it doesn't matter in my case as my chain after can only do much less.
I have as well the room corrected setup with EqualizerAPO and WASAPI and it's good but still, I use the DSD output for music.
Sometimes, after a while listening, I feel something is wrong and ask myself "What's wrong with the music?"; it's either the HS02 which is freaking out adding noise, it does it every few weeks/months, or I left the output to PCM by mistake after testing something.
I'm not really much sensible to any change due to filters but I do find horrible early roll-off filters; even if I can't hear above 13-14k anything that cuts at 17k-18k hurts me.
In a much smaller scale is the same between PCM and DSD output; it's like there's an early roll-off filter that is taking something away.
Sorry I really missed your question.
The foobar plugin is very simple, it's a 5th order SDM and you can't change much.
Completely different with HQPlayer, it's a true monster.
I've found a specific configuration, just one, that works nice for me:

To be honest, it's a bit too much for me HQPlayer; very nice but overkill.
Not only because of the price, money I could spend better to improve something else, but also for the resources.
It requires a lot of CPU and/or GPU for an improvement that I'm not sure I can fully appreciate.
If you really want to exploit the best from HQPlayer you should find the right settings for each type of content.
I'm not that far and I don't have that much free time, I just need something easy to manage.
Foobar for me is the most quick and straightforward way to listen to music.
I got also JRiver on the NAS to stream in the house via uPnP.
But my main listening scenario is always just foobar on the PC via USB DAC; it's quick and easy.
