-If you are using single ended primarily, and you like bright and detailed -Qutest
-balanced and you primarily source from USB, VMV D1
-balanced and you primarily source from coaxial-gustard. The new ess USB dac still has some kinks
-if you need MQA and a high end DAC, the only option right now is the Matrix Pro MQA, at $2000 US. No one has sent one to amirm for review yet, so tread/spend cautiously.
-might want to leave the Audio-Gd alone. Especially at the higher price point. Very poor measurements across multiple devices, questionable warranty servicing for high cost item, I also don't fancy the amanero chips due to noise and driver issues.
The okto has a 9028 inside, no mqa, not a ton of reliability data, since it's a new product, but it sure measure rather impressively!
