@eddy1 Here is another couple of curve balls:
First curve ball: whether you upgrade DAC or not:
Not sure if you just stream direct or if you play files, but if it is the latter this may be worth a read. I admit I am not that computer "tweaky", it takes lots of time to convert and upsample local files, and my DAC is not conducive to higher bit rate files, but this software was developed for the Chord products as they love upsampled files. There is a list of other DAC's that work well with the software.

Second curve ball: upgrade to a different DAC?
Another few comments to digest that I have read lately comparing Gustard DAC's to Dave DAC: The first is from that thread above from an owner of both, and the second is from a review of the latest Gustard, but he also owns the Dave:
"Not much help but I had no issues with the Gustard driver on Windows (build 1903) or Linux, 768/705k worked great and sounded sweeter. Really excellent dac - and not just "for the money". As I've said elsewhere, if I didn't have the Dave, I'd be happy with the Gustard X26pro. "
"I’ll say it right from the start that the X30 is exactly as resolving as the Chord DAVE and exactly as fast and impactful sounding.....In layman’s terms, X30 can do proper justice to live music, big orchestras, and classical masterpieces. And I’m not exaggerating a single bit. The biggest surprise came when the naked Chord DAVE (without the M Scaler) was connected to the same Rockna Wavedream NET via USB and in no time the size of the room felt smaller. The sounds were no longer free and unhindered as they were on the X30. The DAVE didn’t quite live up to its name (Digital to Analog Veritas in Extremis) projecting a shier, flatter, and smaller image in front of me. The X30 on the other hand, sounded exactly how a properly engineered DAC should perform....While it doesn’t outplay the Wavedream Signature, it again outplays the Chord DAVE when it comes to the force behind the bass. When it needs to impress and add a higher sound pressure level, it would do that more impressively. I would never call the DAVE lacking energy in here, but that’s what I’m thinking about when I’m comparing these two... the X30 with its overkill quad mono design brought forward the lost layers of resolution. I can’t differentiate it from my $18.000 Wavedream Signature or $14.000 Chord DAVE in terms of how much nuance there is. Is it as resolving, clean, and transparent? Yes!"
For the price of the Dave you could buy the Gustard X30 and the Nagra and have $6000 left over.
The Gustard is available direct or through Amazon- try it for 30 days, compare to the Hugo and return it if isn't better (?)
