There's nothing 'wrong' with it. It's not bad or anything. It's just not as good as a decent separate option and using it after paying the high price for the DAC itself feels a bit like spending a ton of money on a really nice new camera and then only taking photos in 720p. Still great pictures and better than using a phone, but nothing like the result you can get by taking 4k photos and taking full advantage of what the product you bought has to offer.- Q : you say you wouldn't use the Headphone amp, but you don't say why... I am enjoying it with my Hifiman HE1000 V3. Am I missing something ? Is the internal headphone amp a "weak link" in my chain ?
In the vid I mentioned the Singxer SA-1, that's a big step up, but other stuff like an OOR or a Bliss if you're happy to spend the money would be a substantial upgrade.
