It sounds to me as if the Peachtree is a DAC/Power amp combo. The weakness of not using a pre mp with a volume control is that you are then at the mercy of the volume regulator of the DAC, which apparently this unit doesn’t provide, or the volume regulator of the source, and as the OP implied in his first post, most sources don’t consider volume regulation to be one of their issues. The Node ,because it wants to be the Swiss Army Knife of Streaming offers one, but as other posters have indicated it probably isn’t going to be great shakes.
I would get a traditional integrated amp with a proper volume control and just use the Peachtree as a DAC
. I briefly tried pairing a Node with a Mytek Manhattan DAC when I had to change a tube inthe preamp and awaited the replacement. The Mytek also offered a digital volume control and both that and the volume control of the Node sounded so bad that I wound up putting an unused AVR inthe system as a preamp until the Tube arrived
