I bought this set out of curiosity a week ago, but for the old 2i version. I burned it for 3-4 days of continuous playing with the amplifier turned off. I have to admit that I am shocked how Node is playing now. The sound is more open, airy, diverse, has more depth. Better separation, space between instruments, nothing blends, everything is more accurate. More natural and present vocals. Bass is better controlled, more diverse. Very well rendered all reverberations, rustles. It really is like jumping from 2D to 3D. A change like after buying new speakers or an amplifier. Cheapest sound upgrade of my life. I really recommend. Tested on the internal DAC with interconnects connected as a pre-out to the tube amplifier. In some time I will buy an additional linear power supply, but I did not expect such a change on a regular impulse one. There is also a review of the set by Hanz Beekhuyzen on YT
